Hi guys, I was given a 3G iphone version 4.0.1 The phone was JB and since the fist time I had it the apps occasionally quit by themselves. Lately the quitting has increased greatly and has become a real problem. I live in Spain so i need it unlocked to use my spanish sim card. So i was wondering if restoring it on itunes would be a good idea. I do not need it to be jailbroken, just to work properly. But i do need it to be unlocked. I'm a bit scared of doing it since I've heard is no good to restore JB phones and also i'm new to all this. The phone was bought on the States over the internet so i have no idea which phone company was on originally. What would you do in my place??? I'd appreciate any help!!!
