I've had my Siemens SX66 since August 2005 (this is December 2005).The LCD on my PDA phone cracked after just 35 days of use.NO, I didn't drop it or step on it. I don't know how or why it cracked. The only thing I can think of is I may have had it on my hip in the leather holster that comes with it and leaned against something.CRACKED LCD IS NOT COVERED BY ANY WARRANTY.Once the LCD is cracked you can't make phone calls, or do much else with the PDA for that matter. (You can still answer incoming calls).It cost me $175 to send to Siemens to have LCD replaced.I still love the phone.I strongly recommend you buy the aluminum protective case for it, rather than using the leather holster provided.
