I thought I would let everyone see this... Apparently we will need a new HSPL for the T-Mobile HD2...
As seen here...

I didn't see this untill today and just assumed that it would be the same and we could flash out of the box... I was wrong... and I'm glad I noticed this before I tried it...
Anyway...
Time to wait for the next HSPL...
