I've got an iPhone 3G from the US, unlocked via TurboSIM. I'm living in the UK and am on T-Mobile UK via a Pay-as-you-go SIM.
Unfortunately, I can't receive 3G signal but only GPRS although I've entered the correct APN (general.t-mobile.uk / user / wap) and switched on the 3G and the roaming tab.
Does anybody know what to do? How can I receive 3G via my iPhone 3G over T-Mobile UK?
