CONFIRMED - Yes the Palm Treo 750v is upgradeable to HSDPA!
There's been a lot of debate about whether/if the Treo 750v is going to support HSDPA....

I just spoke with the Head of Palm's Engineering team who confirmed that YES, the Treo is upgradeable to HSDPA.

Palm and Vodafone will announce availability of the upgrade when it's ready!
