Bought my iphone 3gs second hand.It was on the o2 network when i bought it. After i had it a few months, it needed updating, which i did. After updating, it wouldn't work anymore, and it seems to have gone back to factory settings.
When i turn it on, i have to select language, country, wifi etc, and then it begins to search, but iphone screen comes up with - your iphone could not be activated because the activation server is temporarily unavailable. Try connecting your iphone to iTunes to activate it, or try again in a couple of minutes. If the problem persists, contact Apple Support or apple.com/support - and iTunes screen says - We are unable to continue with your activation at this time. Please try again later or contact customer services.
I have since discovered it has been 'jail broken' before i bought it, and it seems to have reset itself back to Orange network, which it was set as the network when the phone was bought new. I bought an Orange sim card to use in it, but still keep getting the same messages on the phone and iTunes. How do i fix it, or is my phone fit for the bin? Any help is much appreciated. Thanks in anticipation.
