"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!"
Yeah... Verizon's had something like this for a while... see below

I used that to backup my contacts last year when i went to windows mobile. It had a backup to outlook option i used, which i then tranferred to my win mo phone.
