HTC myTouch 4G
My only gripe is if it's like the G2, then there's no native access point tethering. Luckily, there are apps for that which don't require bluetooth or a usb cable as they both are bottlenecks.
Better yet, I may wait even beyond this phone, because I guarantee you, this is a sign of things to come!
The Vanilla Android on the G2 is pretty appealing, though.
I'm going to wait and see what HTC comes out with next. I'd like to see an HTC phone on T-Mobile that has the ability to be a wi-fi hotspot (like the upcoming smartphone from LG), but it makes me wonder if T-Mobile would charge extra or if T-Mobile would only put that feature on non-HSPA+ phones.
As for the Glacier, I haven't heard any recent news about it.
