For those who just can't wait another 2 weeks or so, you can go the guerilla route and just directly flash NoDo (7389) on your T-Mobile HD7 today, if you wanted. The process is actually quite simple: you download two ROM files (the old school "ROM Update Utility") and simple flash one, then flash the other.
The first ROM puts a signed Telstra version on your phone, the second, which is much smaller, NoDo (7389). The difference here is the Telstra ROM has the T-Mobile US radios on board, keeping the important part the same and since NoDo doesn't touch the radio, the second ROM is just an OS upgrade.
All in all, the process takes about 10 minutes. You won't be able to backup anything, so this is a clean install, meaning you'll lose any pics or data not saved elsewhere. The other thing is you'll rock some Telstra branding on the bootscreen and a few OEM apps (that of course can be removed), however once you throw in your T-Mo SIM, you can re-download their OEM apps instead.
So how is it? Well, it's NoDo so it fast as heck and we haven't noticed any downsides (it does make the camera better, less pink; also Bing Voice now speaks the Queens English, no joke). On the other hand, it's probably best to just wait a few weeks for the official version. But, if you want to go ahead, read all the directions here at XDA.
