Cany I change the operating system Windows mobile 7 to a Windows Mobile 6.5 on my LG Quantum c900? Okay, normally this would be crazy to do. People pay more money for the latest operating system. But I already bought this phone but did NOT realize that the key programs and files I wanted to load and use on the phone do NOT work on Windows 7 but only any of the older versions. So what to do now? Can't return the phone. Would lose money to resell since already out of box and used.
