Intro This morning I was bored and was playing with my 8125 so I decided to try out some of the various Custom Rom's available from XDA Developers while I was there reading, I ran across several discussions on Windows Mobile 6 "Crossbow" and decided to try one of the Roms that had WM6 in it. Please note: Whatever follows from here is potentially Illegal (Grey Area as far as I know) and also if you damage your device, nobody is responsible but you. I'm simply sharing my experience and view. I will try to post some screenshots later this afternoon. My Review of WM6 So far so good, I'm using a Rom called "XM6" availabe here XDA Mobile 6 (XM6) - Taking You to the Limit - xda-developers Some big changes I've noticed: VoIP Support Updated Appearance and Faster Graphics Much better Sounds and Rings Like Vista mostly Graphic Update Built into the Rom: Total Commander Adobe Reader Smartskey PHM Regedit a PIM Backup utility an Overclock utility Much Much More Main reason I guess why anybody would want to upgrade to WM6 is it supports office 2007, I just wanted to see what it's all really about for myself. So far I have the illusion of speed, things seem to go a bit faster on my 8125, which has been a big gripe for me. The installation went fairly easily, I just had to use my roommates pc as mine has Vista on it and I don't trust Vista to flash (have had issues with vista dropping connection to my pda.)
