[regiteye]

Hello all,
I have a HTC PPC6800 from US Cellular, and im trying to find out how i can get Windows Mobile 6.1 for it? I can not find anything on US Cellulars site nor is my model listed on www.htc.com im guessing i can load the sprint mogul but then what happens if i need to call US Cellular for help that will change default stuff like dial .... to get this info and such right? any sugestions?
i saw a video showing that 6.1 has Texting the way i want showing your your reply as part of the inbox with "me:what you reply" under it. For this alone i want WM6.1 Might sound crazy but rather do that then install cody's thread thing or the springmogul one. any info or ideas is much appricated. thank you.
Also not sure the mogul has Infrared mine does. Mine has Voice Command. Mine doesnt have GPS but some of the 6800 for other carriers might? if i use a rom like that do i lose my Infrared and such things my phone does have that thiers dont?
