Got this as a birthday gift in 2006. It's my second SE phone (first was the T68i).The entire time I've had this phone, never had "ANY" issue with it; no lock-ups/freezing...nothing. The phone simply worked like a charm. Great walkman phone, takes good pics (for a 2MP camera), and perfect size.The only reason I retired this phone, is I got another phone as birthday gift this year; and it's also a SE phoneI HIGHLY RECOMMEND this baby.
