Pocketnow is reporting that, in the next few months, T-Mobile will offer T-Mobile Dash owners the option to upgrade from Windows Mobile 5 Smartphone Edition to Windows Mobile 6 Standard Edition (the new name for WM Smartphone).
This would be a very nice benny. Hopefully, this is true and the cost to upgrade will be none to minimal.
Btw, Pocketnow also has a review of Windows Mobile 6 Standard Edition with a handful of comparison screenshots between the two. Their conclusion: WM6 is just a refresh that makes the user interface look a lot more polished. However, I noticed there is one new feature: Outlook mobile now supports HTML email.
Update: (2/16/2007) Gizmodo is hearing that T-Mobile will allow existing subscribers to upgrade to WM6 for free. Still no exact date but they think it will be within the next few months.
Update: (4/26/2007) Rumors are circulating that T-Mo will release the upgrade on May 4th.
