We had reported that T-Mobile was going to announce their Second Android Phone next week, but now it's officially official. The news was confirmed by T-Mobile themselves. To quote a T-Mobile company spokesperson:
"Next week, T-Mobile will share more details about its next Android-powered phone, the follow-on device to the T-Mobile G1 with Google."
This statement is really just an announcement for a planned announcement with very little detail but all signs are pointing to the release of the T-Mobile MyTouch 3G (aka HTC Magic aka Google Ion). It seems like the rest of the world has access to the Magic while us patriots only have the G1. We can't wait til T-Mobile officially (read: finally) brings the MyTouch 3G to the US!
