Best GSM phone for Mac users?

Hi good cow folk -

I just wonder if any of you out there have a favorite phone (that works with T-Mobile)and sync's well with the MacOS. I currently use a Sony-Ericcson P910a but it was very hard to get and its getting old. I'm thinking that this thing might go belly up anytime.

So this puts me in the market for a new phone that I want to be able to sync and be able to send text messages easily (not with an alpha-numeric keyboard).

So if you have a favorite phone that works well with the Mac lets hear it.

Thanks guys,
eric
