Apparently AWS won't sell the T610, only T616 which doesn't work as well in Europe due to no 800 support (they use 850 due to a contract with another wireless subcontractor). T-mobile apparently will sell the T610 and will even unlock the phone w/ service. T86i seems like the phone to go with for now since the price has dropped and it's not drastically different than the T610 feature wise (the T610 is just much more stylish and has a more polished UI).

FYI, T-Mobile/Amazon.com has the T68i for $99.99 - $100 rebate if you sign up for service!

Nifty features include Bluetooth/USB, E-mail client, picture phonebook, SIM support, Java app support, MMS, games, browsing. Volcanic Red case is sweet.

Decent reviews:
