    Hi all

    Over the last few days/weeks I have begun to experience a problem with my iPhone 4 whereby it loses signal and then simply doesn't regain signal either for a very long time (10mins plus) or until the device is restarted. When this happens, when I go to network settings and manually search for all available networks, only my home network shows (I would typically expect to see Orange, O2, Vodafone an Three all listed too) and even when I try to select my home network, I get the error as picture below. So far I have tried the "reset network settings" option to no avail.

    Does anyone have any thoughts as to what might be causing this?

    Anyone got any ideas or thoughts? Just now I was sitting with nearly full signal yet I couldn't send any texts or make any calls. When someone tried to call me they got a "This mobile is currently unavailable" message. I'd be inclined to think it's a network issue, as a restart and reconnect to the network seems to solve the problem. But then, that wouldn't explain why all of the other networks are missing from the network list.

    Hi all

    As a follow up to this I had tried a restore and this seemed to cure the issue for a while. However, the problem is back again! For 10 hours overnight my phone has sat saying 'no signal' and it's only when I have restarted it that it has managed to regain signal.
