SOLVED! if there are any admins reading this fix should be made accessable as there will be others who eventually have the same issue regardless of the iPhone version… It happens to all of them! After getting zero help from Vodafone or Apple I took someones advice on a forum from overseas, put my MicroSIM into a phone that allows you to enter your own number (this will not work in another iPhone) fortunately for me I got a MicroSIM to normal SIM adaptor with my XT SIM pack I got free with the phone – thanks Telecom! I used a Blackberry Bold 9700, but heaps of other phones allow you to do it. Now my iPhone and iTunes displays my number rather than "Unknown" I can also change it (which I could never do before). The reason it annoyed me is because when your phone doesnt know its own number iMessage will only allow you to send and recieve messages via your email address and wont convert an iMessage to SMS… If the phone you message has no 3G data or isnt on WiFi they will not recieve the message! My apologies for the long story, but I felt it necessary to post the fix as it took me hours and hours to sort it out. Cheers .

Bro, after putting the sim into a Nokia phone, how to input my number there? Pls explain in details on how to do??? Many many thanks.
