So I have still not switched permanently to an Android phone.  The main remaining reason has been that I simply have no cell coverage in my house.  With my T-Mobile Blackberry I have been able to roam seamlessly onto my Wifi network at home for several years now, using UMA.   Well, T-Mobile has finally announced that they are introducing UMA for several Android models, starting with the new MyTouch and the Motorola Defy.  Not sure I like either of these very much, but T-Mobile is planning to add more Android phones to the program soon (the G2 looks interesting).  In addition to being convenient, it also helps save money.  For instance, when I was just in London and Berlin, half the time I was making my calls over Wifi networks.  If you pay an extra $10/month, all those Wifi calls are included, which sure beats international roaming.
