conversation cut off and show apple logo
My iPhone 3GS got problem now, when I make converstion (call or receive) for more than few minutes, I got line cut off and the iphone showed apply logo. I had to take few minutes to reset it or recharge it although it had already almost full bettery.
I read from a forum / community they said have to "replace the device"...
Please all help. Thanks.
iPhone 3GS, iOS 5.1
