I have restored this phone a zillion times and after about 2-3 months of use I get Dual text sounds while in a chat, and while the phone is sleeping somtimes I get no alert at all phone doesn't vibrat,alarm, or light up like I received a txt. It just stays black and then after the minute or so I get the alert which is the second alert that I have a msg.

The only way to explain it is while in a chat the normal WHEW sound is now WHEWW WHEWW.. LOL

Jailbroken with blackra1n 3.1.2 firmware.

Id like to find a solution as I am sick of restoring the phone to get it normal for 3 months and then it stats with this crap again...
