MDA Pro is 3G. Bulky as fuck though.
O2's XDA Atom is really nice as well.
If I were you, wait. Give it a bit longer, unless you desperately need a phone now. All the mobile phone brands are in transition mode, only Himalaya (the makers of O2's XDA's and T-mobile's MDA's) have made 3G PDA phones, but they're not perfect. Wait for the follow ups, like an XDA Atom-II or something
