Quick question on unlocking 3g

I am trying to unlock a friends 3G iPhone for use on T-mobile, it is jailbroken 4.1 and the baseband is 05.14.02...

Is it possible to unlock with this baseband? I usually just used iclarified tutorials, but they don't list this baseband...

Please help asap
 
I have a few questions as well..

I have an iPhone 3G, that I restored (never jailbroken, had OS4 installed but assuming it is back to 3 with the restore)..

It is currently locked to the Rogers network, but I am selling it to my cousin who wants it on Bell..

Do I have to jailbreak it before I can unlock it? Once unlocked, can they perform regular updates via iTunes or will that relock it?

I have never jailbroke/unlocked a phone before, so any advice would be appreciated...

#1 Yes, In order to unlock, you must first jailbreak the iPhone (only way).

#2 No, if you update the iPhone through iTunes, the iPhone will re-lock. You can only update if the tools to jailbreak and unlock are out for the newest iOS update.

One thing you might want to know about Bell is that their network until last year was essentially CDMA/EVDO. In 2009 they implemented an HSPA overlay which provides a 3G capability that works with the iphone. I believe this was done in conjunction with Telus.

What it means is that you only have 3G service available for the iphone on Bell no fall back to GSM/edge if you get poor reception. This is unlike Rogers which has always been GSM and hence provide both GSM 2G and 3G.
 
Great, thanks, I will give that a try tomorrow, I don't have the iPhone with me at this time...

Do I need a sim card it in to perform the jailbreak? When I give it to my cousin to set up with Bell, is there anything he needs to do?

Sorry for all of the questions, if I was the one doing it for myself I would be fine, it's just where I am handing it off to someone I want to make sure it is going to be a smooth process for them...

As for the Bellus (Bell/Telus) network, they put the HSPA overlay over all of their towers, so as far as reception goes I think it will be okay....They actually have more HSPA coverage than Rogers...but thanks for the info 🙂

If you use PwnageTool to jailbreak, you'll need the official sim (yours) to activate the iPhone. There's nothing really that your cousin has to do from then on. Just tell him not to update or restore the iPhone or he'll lose everything including the needed unlock.

I have upgrade to an iPhone 4, so I have a new sim card for that phone...Can I use my now-unactive sim card from the iPhone 3G to put in it to jailbreak? Or does it need to be "active"...

Thanks for all of your help...
 
The sim card has to be active but you can run GreenPois0n or LimeRa1n over Pwnage to "hactivate" the iPhone.

No problem.
 
Oops, forgot to ask...Could an Active Bell Sim be used instead to unlock it, instead of going the Hactivate route...

Hactivating won't affect the iPhone if that's what you're thinking. I don't have much knowledge about Canadian carriers but you can try.

I was thinking more along the lines that I don't have an active Rogers sim to put it in and thought that might be easier than trying to hactivate...

I found the link to GreenPois0n, but it doesn't suggest that it supports the iPhone 3G...will it work?

I restored my iPhone, so I'm assuming it is back to the original OS..How can I update it to OS4? Can that be done during jailbreak?

Again, sorry for all the questions...
 
The sim to activate the phone on the carrier that its locked to doesnt have to be active.
Even old inactive sims will activate the phone and get you into the homescreen.

Asking questions is how you learn, no problem. I forgot you had a 3G. GreenPois0n is not going to work for 4.0, you'll need Redsn0w 0.9.6b2

To update to you can find the iOS ipsw files here at: http://iclarified.com/entry/index.php?enid=750

But don't update the iPhone just yet though iTunes. You have to use PwnageTool first. Follow this guide here: http://iclarified.com/entry/index.php?enid=12363
 
Awesome, I just wish I had the iPhone here with me so I could do it now, lol...It'll have to wait until tomorrow night!!

Thanks to all for your help! 🙂

So to be clear.... I use Redsn0w first, and the the Pwnage tool?
