I was excited about IOS 5 so after a while of failing attempts I managed to get it on my phone. And now another problem I cant Activate my SIM card, I think the problem is with the SIM card itself since its an old one, and I had problems with it before, and wasnt using it. Since Im taking classes in a foreign country I just bought a crappy prepaid cellphone for comunication and used my Iphone as an Ipod and to manage my activities at school before instaling the new IOS. I cant get my hands on a new SIM card, since Im out of the country... :S What can I do to activate my Iphone? I really need it for school. Any help is appreciated, thanks.
