Later this summer, it would appear that Palm is planning on releasing some ROM upgrades for their devices.

Of particular note is the Windows Mobile 6.0 Professional for the Verizon Treo 700wx. Note that this is not a Windows Mobile 6.1 Professional upgrade and it will not be made available for the Verizon Treo 700w. (The Treo 700w has 32MB of RAM versus the 64MB on the Treo 700wx.) Palm is also reportedly working on two minor upgrades for the Sprint Centro and Treo 755p for Verizon that will likely be released later this year.
I honestly never expected this update to be released for the Treo 700wx. I'm glad to see that Palm will be releasing the update. A lot of Treo 700wx customers have been asking for it.
