i jailbroke my iphone 4s so i could switch from verizon to tmobile, everything went fine, but when i want to go to my voicemail i come to the voicemail of vodafon, from holland, and i cant switch it off because i need a number from vodafon to be able to switch it of but i dont have that... any ideas why this could be and how to fix it?
thank you already =))
