... and there was much rejoicing (yea). Here's the link to Palm's Treo 750 Updater 2.25.
Of course, yours truly has been running WM6 on his Treo 750 already... but only because running 'unsupported' software is a way of life for me ;)
Note to AT&T: What took you so long? Recoup some customer sat and come clean with the technical difficulties around this update. Treo and Windows Mobile forums haven't exactly been singing your praises lately. Heck, your own forum has a discussion thread with 300+ replies dedicated to the misleading communication about this update. This situation brings to mind the story about how Lexus handled their first big recall in the US. You can read about it in the Time.com archives. I really don't think AT&T is adhering to the "Lexus Covenant" of customer service, which states in part "Lexus will treat each customer as we would a guest in our home".
