I have a 3G from Movistar (Spain) and want to be able to use a UK PAYG Sim when i am in the UK instead of paying OTT Raoming charges. Downloaded and installed the Pwnage Tool, everthing working perfectly on the jailbroken phone , native SIM, Wifi, Mail.. got the Cydia and Installer programs on phone, Pineapple Logo etc. But the phone will not recognise a different SIM card. I have a vodafone SIM (again Spanish) which wont be recognised by the Iphone. No error message, just no service. I went through the expert mode on Pwnage and deselected the activate checkbox.. tried everything i could think of... over to you guys .. i am stuck..
