After 6 months of flawless service, my Treo 600 GSM (ATT Wireless) locked up, started flashing the Palm logo screen until the battery died. I recharged it and it seems to be working (albeit less all the information I had stored in it). The question: should I recycle the phone through the warranty exchange for a refurbed unit or take my chances with the one I have, banking on the prospect that it was a random event? Second question: is there a way to store my favorite numbers to the SIM card?
