so i was talking on the phone with my friend and then the call dropped, when i looked at the phone it had a white screen with an hourglass. so i pulled the battery for about 45 secs, and when i put it back in the same screen came back up. i did another battery pull, to no avail. then out of nowhere it just boot up itself to the at&t logo.
Did it twice last night, after my call is dropped, just goes to hour glass and sits there for a while waited to see if it came back but nothing. Once I pull the battery then it reboots and verifies software,etc, then finally I can make a call again...very annoying.
