Hmm.
Well as I mentioned the phone had been jail broken quite a long time ago (when I first got it). I only wanted it for the simple reason that IOS allows me to (or should do) access an online chat service where I join up with chums of a weekend and we talk about football as it's happening. They're a great bunch, but now that I have a proper Sky subscription I no longer need to watch matches on a stream so I still need a laptop or desktop running so I could chat with my chums.
Well I tried to access this service using the phone "as it was" and nothing was happening. So in the end I plugged the phone into the PC and ran Itunes and restored it to "un jailbroken" and quelle surprise it worked and I can now access the chat service
This is very handy because it means I don't have to sit at my desktop or have my honkingly large laptop on my lap (trust me when I say it's like sitting with 50lb of bricks on your lap)
So in the end the fix was to put it back to stock
