Yep most of the Sony Ericsson phones have software faults. Most can be sorted by powering off the phones and powering them on again though this can become annoying. I have a Sony Ericsson now saying that and its been great. One small software fault since I've had it but it is one of the newer walkman phones. The u600 is a great phone and dont suffer the Ericsson faults just I think it looks horrible. Good luck with your choice Stamper
