mine is the same here.. side note: how many sim card did u go thru spaz? haha jk :eek::D
 
From what I can tell with my testing the Original 2G iPhone will only work with one SIM card at a time. Usually this is the one it came with, but it doesn't have to be, it just has to be a valid SIM card it activates successfully with. Once activated with a valid SIM card, it will only work with that one and force to you itunes to setup a new plan if you plug in a different card.

I ran some tests:

2G iPhone jailbroken and unlocked and ran with whatever sim card.
Restored to default 3.0 using itunes with no sim card installed.
The phone complained and wanted me to activate
Plugged in original sim card with no active plan and wanted to connect to iTunes to activate (thus the unlock is gone and not permanent)
Activated fine within seconds
Put in iPhone 3GS sim card and it tries to force me to start a new plan.. again no permanent unlock here

Next I restored again with no sim installed
Plugged in iPhone 3GS sim first and it still wanted me to setup a new plan
Swapped out for the original sim and it activated immediately

This tells me it is likely that the 3.1 beta has changed this behavior. I don't have 3.1 to confirm however.

Your test results are what I'm used to in the past. That's what I've been trying to tell people. When you unlock the iPhone, it relocks when you do a full restore. In the past, I would have to jailbreak an hacktivate in order to even use the phone after a restore. The fact that 3.1 activated automatically (through iTunes with a card it's never seen before) without having to set up a new plan is what amazed me.

New 3.1 feature: Use any AT&T plan on the first gen iPhone :)
 
Your SIM card is the one that's activated. It has nothing to do with 3.1. When you take an already activated SIM and place it in an unactivated phone, BAM it activates. There's nothing magical about your SIM card.

That has never been the case in the past. That's what I'm trying to tell you.

The first gen iPhone was never like that in the past. If you stuck a new card card in it that has never been activated in that phone (like my brand new iPhone 3G card), you have to go through the process of setting up a new plan in iTunes before your iPhone will activate. Trust me, I've had plenty of first gen iPhones (4 different ones to be exact) and I could NEVER activate them officially with the card from my 3G. However, once you go through the setup process an activate a first gen iPhone with one particular card for the first time, it will always activate with that card whether you have service or not. Even if I stuck in the previous owners deactivated sim card, it would still activate the phone and allow me to use it as an iPod, but as soon as I took it out and popped in a different card, the phone would re-lock and give me the "Connect to iTunes" screen until I put in the other card again. The first gen iPhone is not like the iPhone 3G.

On 3.1, this wasn't the case.

Also, if you could pop any activated card into a first gen iPhone then why do people still have to "hacktivate" to use other plans (such as go-phone plans)? I've always had to hacktivate in the past to use my first gen iPhone as an iPod touch.

Oh, in case I haven't mentioned before... In the past, I've tried putting my 3G sim card in my first gen to activate it and it didn't make it activate.

But it is, trust me. Otherwise my activated 3G SIM wouldn't have worked in my unactivated 3GS when I got it. When I removed the SIM and put the one that came with it in there, it didn't work. It's the SIM, not 3.1 or anything else.

You're dealing with a 3GS and a 3G. That's a lot different. The plans don't change between those phones. Nice try there. Trust me, it's a 3.1 thing if it's not the card.

Look at a few posts up and see the guy who did some tests on his first gen iPhone. It won't activate automatically with a 3G card *unless* that card was used to activate it in the past (by going through the iTunes setup and picking a new plan). If the first gen iPhone sees a card that has never been used to activate it, it's going to go to a special page in iTunes to help you set up a new plan to officially activate it.

Why don't you believe me?

Here's some information for you (from this official document):

"Activation for an original iPhone requires that its SIM card stays with that iPhone. If the original iPhone displays the "Connect to iTunes" screen, you can use that SIM card to re-activate your original iPhone, regardless of whether that SIM has a wireless service account/tariff still associated with it.

To re-activate an original iPhone that displays the "Connect to iTunes" screen:

Reinsert the SIM card used when original iPhone was activated and had a valid wireless service account/tariff.
Connect original iPhone to iTunes on a computer connected to the Internet
If that exact SIM was previously valid and used with that original iPhone, iTunes will re-activate iPhone. If the SIM no longer has a wireless service account/tariff associated with it, original iPhone will still be activated, but without any cellular service."
 
that is what all of AT&T's new sim cards look like now

you say the sim card you put into the phone is activated for your other iPhone?
what your phone is exhibiting is COMPLETELY NORMAL behavior, even if the phone had not been unlocked, when you pit a SIM Card in there that is activated for an iPhone, it will work on your iPhone...as soon as you plugged it into iTunes, iTunes was like "Hey, that's a valid SIM card..." and it works...normally

The original iPhone has a different data plan than the iPhone 3G. This is why you cannot simply put a sim card that has only been activated for an iPhone 3G into an original iPhone. The original iPhone will only activate if that card has been previously used to activate an original iPhone by going through the iTunes steps of picking your plan options. So therefore, in the past (before 3.1) I couldn't use my iPhone 3G card to activate my original iPhone because the card that came with my 3G did NOT come with my original iPhone.

Here's what *should* have happened: iPhone asks for sim card to activate. Pop in my sim from my 3G. iTunes takes me to a setup screen where I have to enter my SS# and pick my minute and text packages. This would have downgraded my sim to use the $20 data plan and free 200 text messages. This is how it has always behaved for me. Trust me... I've owned enough first gen iPhones to know what happens.

Here's what actually happened (only on 3.1): I restored my iPhone (not update) to 3.1 and did not preserve any of my previous backups either. I got the purple "Connect to iTunes" screen (which I figured I would get). I realized that I left the first gen iPhone sim card at home so I was out of luck because I knew what would happen if I put my 3G sim card into it. I figured it couldn't hurt to try anyways, just in case it did work and within seconds, it activated (without forcing me to pick a new plan) and I was on my way. Push also worked flawlessly.

I can't make it ANY clearer than that. If anyone wants to try it go ahead. Restore to 3.0 and insert your friend's 3G sim card to activate it. Good luck, it won't work. Just make sure you're restoring a first gen iPhone (silver aluminum back).
 
Because its not Activated. Unlocking and Activating are 2 different things.

Exactly.

My iPhone "activated" automatically with the 3G SIM card... it shouldn't do that. It's supposed to deny any SIM that didn't come with the original iPhone.
 
Just an update. I restored my original iPhone to 2.2.1 and stuck my 3G SIM card in it and it will not activate it anymore.

It's definitely a new 3.1 feature. In 3.1, the original iPhone will activate automatically with any AT&T SIM card.

Sweet deal!
 
Heh, I work for at&t the orange backed SIM cards are just the newer SIM cards we have there is nothing different about them.
 
It just might be a new color they always change the sim cards.. i have 3 versions.. yes it could be your unlock stayed after all. and whats the "Pink screen of death"?

magiccccccccc!!!!!!!!! :rolleyes:
 
I think 02 did the same sort of thing with 2.0 and Pay and Go.

Once I updated using a restore. I put a Pay and Go sim in and it activated by itself.

I dont have the phone anymore so I cant test anything. Anyone else have the same results?
 
But it is, trust me. Otherwise my activated 3G SIM wouldn't have worked in my unactivated 3GS when I got it. When I removed the SIM and put the one that came with it in there, it didn't work. It's the SIM, not 3.1 or anything else.

When i put in my grandfather's AT&T Go-Phone sim card into my brothers activated 3G, it works fine, no need to do anything. When I put that same sim card into my Original activated iPhone, it tells me to connect to iTunes, and wants me to set up a plan. Same thing with a t-mobile sim, i put it in my brothers 3G, it doesn't lock up, just no signal, put it in mine, connect to iTunes.
When a 3G/3GS sees an AT&T sim card, it will work, when an Original iPhone sees an AT&T sim card, it will tell you to connect to iTunes for Activation. thats what the Spaz is trying to say. How ever when Spaz put his AT&T sim in his Original iphone, it acted like the 3G iPhone does when it sees a new sim.
Am I right?

Right on the money! 3.1 allows the original iPhone to act like an iPhone 3G (as far as activation goes). With 2.2.1, it wants me to set up a new plan for my 3G's SIM card, but 3.1 activates with it with no setup.

I'm glad i'm correct. I just hope, 3.1 keeps it that ay. I would love to have my Original iphone activated, take that sim out and move to Go-Phone.

Be careful! My brother (iPhone 3G user) used my sister's SIM card (from BlackBerry Pearl w/o data plan) for about a week... not sure if he had WiFi turned on the entire time or not... a month later, they got billed some $1,600 in data usage charges! I think they were able to work it out with AT&T since the iPhone 3G did have a legit data plan...
