iPhone 4 unlocked and still can't get T-Mobile

[CaptMurdock]

The God of Frustration (who looks a lot like Daffy Duck) is hitting me hard these days.

I finally managed to jailbreak my iPhone 4, install Cydia, install various versions of ultrasn0w, get a microSIM card, had my old T-Mobile prepaid number transferred to the new microSIM...

...and I still can't get it to work! Every instruction I have seen says "Go to Setting -> General -> Network.." and enter in the strings of numbers, etc.

My problem is: under General, there is no Network tab! "Cellular," yes, but that just deals with Cellular Data and enable 3G. Under my About tab, the Network tab says Not Available.

iTunes isn't even letting me sync the iPhone because the SIM card is not supported!

What the hell am I doing wrong?

Why not save yourself the trouble and do a factory unlock?

 

[CaptMurdock]

How much is that going to cost me?

A few bucks on eBay. Are you from the US? If the phone was purchased after Jan. 26th, 2013, it's illegal to factory unlock now, but if before, you're fine.

Yep, wish it was as simple as just jb and install ultrasnow.
Ultrasnow only unlocks baseband version 01.59.00 for the i4
Go to settings,general,about and see what your modem firmware version is.
If its not the one I listed above your only option is to purchase an imei unlock.
It's only $2-3 for an AT&T iPhone unlock. I'd go with that if I was you.

^I'd rather use tin cans and string than use AT&T. thanks anyway.

That's not what I meant
If its an iphone locked to AT&T you can purchase an imei unlock for it for cheap.
Then you can use it with tmobile USA or any GSM carrier in the world.

^Gotcha. Thsnks for the info.

Anyone know any cheap UK factory unlocks? or any websites selling unlocks in UK Pounds instead of dollars?

This looks good. I'll try it out and get back to you. Thanks.

Done! Went on eBay and found this link. $5.99 and they were able to unlock my iPhone within 24 hours. Now I have my T-Mobile pre-paid number on it. Yay.

Thanks for all your help!
