i need to ask for iphone owners help.
yeah.. i know.. wrong forum. but I am not a member of any iphone forums. :P
my girlfriend.. she has an iphone4. it is from AT&T.. but she had someone unlock it so that it can be used on T-mobile. I am guessing it is jailbroken too (since it has to be..so you can unlock it, right?)
it is still on ios4.. not sure of the exact version.
the issue is that..
when it reboots or battery dies.. it has a very hard time to get/find T-mobile service. She has to go through a very long procedure when booting up. takes over 5 minutes.. and it still might not work.. and she has to start and reboot.
a friend said.. that it is most likely that the original unlock method used was not a good one. I need to find a better unlock method.
here is one method i found: How To: Unlock the iPhone 3G/3GS/4 on iOS 4 - TheUnlockrTheUnlockr
1. can i assume her phone is jailbroken?
2. has anyone used this method? or have a better method?
3. since, it is already currently unlocked.. what must i do so that i can use a new unlock method? Do i "relock" it, if so what method?
4. once i use the new unlock method.. and assuming it goes well.. do i just put in the sim card.. and it should find service with T-mobile and work?
dont know what else to ask.
