Cannot Activate iPhone?
Stupidly, I restored my phone last night - and now when I plug it into iTunes and come to activate it, it says the SIM card is unsupported. Now, I don't actually have the original SIM card as I bought it second hand, so therefore I don't know what network it's actually locked to. I'm in the UK and currently on O2.
Firmware version is 4.2.1
Baseband is 05.15.04-6.4_M3S2
any help guys?
Good news: as you have a 3G iPhone, you can jailbreak the phone and hacktivate pretty simply. iClarified - iPhone - How to Jailbreak and Unlock Your iPhone 3G Using RedSn0w (Windows) [4.2.1]
Bad news: if you rely on carrier unlock, your restore of the phone has updated your baseband to a version that can't be unlocked by ultrasn0w
If you rely on unofficial unlock, your only option is to use the following technique Dev-Team Blog - Ultra-recycle
Please note that this comes with significant drawbacks, which you can read about in the link above and also in http://www.hackint0sh.org/f204/196391.htm
if the phone is locked to a UK carrier, it might be smarter to ask them how much an official unlock will cost.
Thanks for the quick reply Olethros, but I can't get onto the iPhone section on iTunes because it says the SIM is unsupported. Therefore I can't complete the steps you suggested. :(
I'm a bit of a newbie when it comes to Apple, so I have no idea where to start! :S
okay, so I got back into my iPhone - I jailbroke it and I installed Ultrasn0w so that I can unlock it.
The current ultrasn0w release skips my baseband and now I can't use my phone at all..
any help guys? :(
