USB + WiFi = TWO phones...??

[deveds2]

If I sync using Wifi, it works GREAT! BUT, when I sync using USB, Winamp thinks it's a different phone and syncs it in an entirely different way (tracks get deleted, etc.).

Any way to fix this?

possibly

WinAmp tries to use ID3 tags to rename (!) your files -- sounds like exactly why I moved away from iTunes... Anyways, make sure that after you are sync'ed, preferences under:

Options - Preferences --> Media Library --> Portables
Options - Preferences --> Media Library --> Portables --> DeviceID
Options - Preferences --> Media Library --> CD Ripping

have filenaming conventions that match your PC.
