Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
i believe the 'u' in the model# means it will be a UMTS phone, and LG does have a music player in Cingular's CU500(also UMTS). VzW's exclusivity is only with that particular chocolate phone, which would have to be redesigned with gsm at least before tmo or cingy would pick it up anyway.
