so lately i've been noticing my iphone is constantly "searching" for signal in places were i used to get 3GS signal/service (full bars) all the time. now, i was ready to blame at&t outright, but lately whenever this happens i've been "reseting" the phone (home + sleep buttons) and after the reset i get full 3GS service again.

why is this happening? is this an at&t issue, or an iphone hardware issue? why do i have to reset the phone to get a signal?

Macbook Aluminum 13 Inch, Mac OS X (10.5.6)

    Im having the same issue and so is a co-worker. We both have 32GB 3GS iphones. Hope they fix it soon.

    Welcome to OS 3.1. The day after I upgraded my 32GB 3Gs this started. Hoping for fix soon.

    Try a network reset under Settings - General - Reset - Reset Network Settings. It won't erase anything, just reset the network on the phone. I had the same problem and this helped.

    I too have 32Gb 3GS and work in England but live in France. In our small remote Champagne region village all network providers share a local network - that is to say SFR, Bouygues, Orange all use the common F-CONTACT network. I had no problems prior to 3.1 upgrade but now can only get service where there is a direct SFR, Orange or Bouygues signal. If I go to a town where the main providers have a signal, everything is fine but back home I now possess the only phone in the village which cannot connect to a service. O2 are unable to help me and suggest 3.1 may be to blame. My question is simply, is there a way to downgrade back to 3.0 somehow?

    just "reset networks" we'll see if this works. i don't have my hopes set too high.

    Thanks for your suggestion but I tried that (several times) as well as restoring from backup and restore as to a new iPhone. I have switched off, removed sim, in fact everything that has been suggested by every support person I have spoken to at O2 and Apple. They seem to concur it is a network issue not the phone so I am going to buy an O2 sim today and take it with me to France tomorrow when I go home. I will try to use another phone (not iPhone) with O2 to see if it connects and also try to use my own sim from the iPhone in another phone. This will at least prove where the problem lies - though it will not resolve it of course. I am expecting to find it is the phone, not the network. I'll report back after the test.

    It could be the network but it would be a big coincident if the networks both here in the US and there in France started messing up at roughly the same time as OS 3.1 was released. Agree? I could almost accept the coincidence if only two things happened at roughly same time but three. NOT.
