Hi, i have an iphone 3g jailbroken and unlocked that has been acting really dumb lately. i jailbroke with this http://www.ifans.com/forums/showthread.php?t=295129 and the iphone has problems which include: - Apps closing when clicked - when apps do decide to open, it taked about 5 minutes... literally (i timed) - Music & video dont (it shows the "play" image in lock screen and top bar but no music comes out) --- music sometimes decides to play but acts like if its an ipod touch (doesnt use speaker) - text messages receiving and sending texts like 2 minutes later - youtube doesn't work (cannot connect to youtube) - loses battery; even when off. im not sure why this is because when i jailbroke it i did not apply the backup. which means that the phone is clean. it has 343 songs, 4 movies and 28 apps; 16gigs. and the only thing i downloaded from cydia was the unlock, and thats it from cydia. help?
