The first treo 650 i had new sent from telesales was perfect as far the sound issues people talked about on here but then it crashed eight hours after.....when i got this new one the other day since iv had it people keep saying my voice is choppy and they cant hear me n this is literally on every call. so I assume this is not in every unit since it did not happen before on the other one. IS there a way to fix this or should I just go to the store and they will replace it for me again? Please let me know ASAP its real annoying
