Windows Mobile 6.5

i think its better u go for windows 6.1 os....there wont much difficulty in operating...for windows 6.5 its better u should ve HTC touch diamond or later

as regards graphic and function i think the 6.5 version is much better than other windows mobile versions of the past so the 6 or older...in reality if you want upgrade you must check before your cell configuration and some other related to the 6.5 because normally i guess you couldn't upgrade because the new version needs more ram and rom too...but not very sure about it so you must first check those parameters before thinking to upgrade.

If you haven't upgraded already, I suggest you do. Windows Mobile is good but their latest version has a lot of performance updates and bug fixes. Only problem you may have is having enough memory to support it. I had a phone with 6.5 on it and I had hardly any problems with it. Only thing wrong was the keyboard became difficult to use and it started having some issues, but that's because the phone is about two to three years old and I've switched phones since then.

hi...i think u cant upgrade to 6.5.....the one who is using 6.1 and 6 can be eligible for upgrading to windows 6.5....i think u should go for HTC THOUCH diamond2 or HTC TOUCH HD.....both r damn good ppc
