Okay my treo 650 is a cingular unlocked gsm. It has been working great but is now useless and i need to fix it if possible. When ever i start it up it immediaely goes into a hot sync loop. whenever i hit cancel it returns to hot sync mode. If i can put the key guard on as soon as i start it up it wont go into the hot sync loop, but its useless becasue as soon as i undo the guard it starts it right back up? please help and offer any advice.
