I have created an updater that can upgrade your TREO 700x or 700wx to Windows Mobile 6.1 Professional!

I modified a Sprint SD Card updater package and created a 6.1 (unbranded) updater!

Basically, I left out the Sprint radio settings so that your current provider's radio settings stay in tact, and only the operating system is upgraded.

Windows Mobile 6.1 Ugrade!
