Iphone keeps locking/unlocking after jailbreaking with blackra1n
Hey everyone i hope you guys can help me becasue i have a bit of a problem,
well first of all i jailbroke my 3.1.2 iphone 3g with blackra1n then i installed cydia and everything was fine my phone was unlocked and i was able to use my simcard,wi fi, and every other thing the iphone has to offer, but i realized something weird my iphone time to time locks back up and when i try to call or msg anybody it tells me that it has been blocked to this carrier, mind you after a couple of hours or sometimes a day it will automatically unlock again and i will be able to use it and make calls and messages. The weird thing though is that my 3g works fine i am able to use safari.youtube etc...
Dont get me wrong im very appreciate that i am actually able to use my iphone but it just gets annoying because i have to switch from phones until my iphone decides to unlock itself again, i would really apperciate if any of you could help me solve this problem....
When it does lockup i open rain and reinstall cydia and snow but its still locked until it actually decides to unlock itsself, any help is highly appreciated thank you for your time
Iphone 3G 16gb capacity
