Keep in mind though that the rest of the world pretty much uses GSM not CDMA.
That being said - Micro$oft is clueless when it comes to mobile and their marketing for it is just plain stupid. (Like the MS Kin for example)

>Last week I said MS would not make it in the phone market with WP7 because they won't support CDMA until mid 2011. That means it won't work on Verizon, the largest carrier in the US, nor on Sprint. This is just another nail in the coffin. If I were an MS shareholder, I'd be begging SteveB to stop throwing money into this area and just conceed it to Google.
