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!"

good point. Will Visual Voicemail work?
it is my understanding that visual voicemail requires apple software and servers running on the particular network to process the job, therefore i believe visual voicemail is an AT&T only at this point in time.
you're right. If using another SIM in iPhone (after unlocking it), when you hit the voicemail tab. It dials a call to your carrier's voicemail
