Ok, something weird happened today. My iPhone worked fine since last thursday. This morning I wanted to open Safari while I had GPRS. Safari loaded for ages and than crashed (back to homscreen). Since then, I have no mobile data available. The network reception is fine and I can make calls, but no GPRS, no EDGE or 3G. Also, since then I see that spinning wheel for Internet Tethering (which was not there before) and I can't stop it. I tried to restart the phone and to reset the network settings - nothing helped, no mobile data. I'm on Orange in UK and I also do not have any settings for mobile data like APN, they just do not exist. Has anyone an idea?
