I just had my 6030b flashed with unbranded firmware (v3.31) by iUnlock. Does anyone have any experience with 3G SIMs allowing manual network selction? Does it depend on the phone and/or which firmware the phone is flashed with? My 64K SIM still blocks it, as well as my old 32K. I tried my cousins 3G SIM that is about 6 months old he said, and it still blocked it. Do newer 3G SIMs allow manual network selection or is there a better chance with the newer ones. Any help or suggestions are appreciated.
