My 1.1.4 iphone was originally unlocked with iLiberty.. I have been using the same setup for almost two months no problem.. Recently, my iphone is starting to give me trouble with wifi.. sometimes it see the wifi networks but doesnt connect.. I tried opening my wifi network completely with no passwords.. sometimes it connects and connection gets lost in seconds.. Its not a signal issue since I even tried doing the same by sitting infront of router.. now iPhone just restarts if I try to use wifi.. all other functionalities work fine just not the wifi.. so, I tried to winpwn it and it still have the same issue..
