Hi This phone has been working fine until the last couple of days I haven't been able to use the internet, it just said that i was not subscribed to an internet provider. Spoke to tmobile and they went through all the settings and couldn't find anything wrong their end and said that I need to restore my iphone which i did last night but now it fires up and it keeps beeping at me at about every 5 seconds and then the screen goes blank and then beeps again and is just stuck in this cycle. I can see the slider intermittently between the beeps but will not move. I have tried rebboting and this does not clear the problem. Hope this makes sense, any ideas?
