Hi, I'm in the UK and have an iPhone which is activated on the the O2 network with one of the iPhone tariffs. Yesterday I unlocked my iphone in order to benefit from the third party applications etc. However I never unlocked the phone for it to be compatible with any other than the intended sim card. After fooling around with 3rd party apps the novelty ran out and I missed my visual voicemail which is more beneficial to me than the provided apps. Therefore I restored my iPhone back to factory settings. The phone's just as it was when it came out the box. Except that I can no longer browse the web using safari unless I'm connected to a wifi spot. That is, I get this message : Cannot activate EDGE. You're not subscribed to the EDGE network. Furthermore my visual voicemail won't work. I cannot use google maps (which is very useful for me!) or any other application that requires 'internet' unless I'm connected via wifi. Should I contact O2? I'm scared they cannot help and will know that I unlocked my phone. Please reply. Any help will do, especially if you've been in this situation and have rectified it!
