LG Neon GT365

Hi, I have an unlocked LG KS360 that I bought from Ebay to use with my AT&T sim card. This phone is basically the same as the AT&T Neon but Orange branded for Europe. Well after buying it i realized that it doesn't have the 850MHz Frequency to use with AT&T so I would sometimes lose signal in certain places. Also I don't like the Orange branded firmware on the phone that doesn't let me set up WAP and picture messaging for AT&T, so I can't send picture messages or use the internet. Also there is no IM applications on it except for windows live messenger, which unfortunately for me, is the only one I dont use since I only use AIM & Yahoo messenger. So all in all im screwed in so many ways. Is there an unbranded firmware out there or does anyon...
