Hi guys, i flashed WM 6.1, but some problem i have. My radio is always lost and searching a network. I tried all WM 6.1 ROM, but still have this problem. on WM5 all is Ok.
My radio Rom: RS00052

may be some how you switch BANDS 900/1800/1900 and your local network provider is using only 900 ? these is my lucky guest
