It may be damage to the dock connector which has the antenna on one side and the mic/speacker/dock on the other. try opening and reconnecting the dock or replacing if that doesn't work

also try removing and cleaning sim and then replacing

I had the same problem. It was the antenna. 'Fone Doctor' at London Bridge Station fixed mine for £38.


cool and if you follow pollytintop's advise, you can save that money by doing it yourself.


Handy only for those living near or using that tube station, but not for anyone else.

I had the same problem and I fixed my iPhone 3GS.

I follow the comments here, got the link how to change the dock part. I went to the eBay and bought a new dock part (this is where the antenna is). I paid £5.99 in UK. I open the iPhone and changed it... it worked fine but stopped after a week. I open and disconnect and connect everything again, but didn't work, so I remember when I went to Apple the reset all networking so I did it and all working now.

I hope it help. Good luck

I dropped it thrice in a month recently (ouch!) (this was in addition to dropping it in water...) - and had no-signal to one-bar...

-- The first time, I tapped it in anger at various parts - and hey presto, the signal came back full strength!

-- The second time I took it to the repair shop as no amount of tapping made any difference. The shop said they do not repair the 3GS as repair costs are more than a new phone...I begged them to take a look, they agreed...and when I came back in one hour, the young guy behind the counter said he had "reset the signal; only took him 30s" and it was back in business. As usual, I did not ask him what he had done...

-- The third time - almost too ashamed to take it to the shop again - I tried resetting signal -

>> toggle airplane Mode

>> Settings -> General -> Cellular (toggle)

>> Power on/Off

>> SIM remove/re-seat

- but no effect

So I took it to the shop again and another person behind the counter. "What is it," he asked me when I showed the phone. "A 3GS," I answered. All round laughter in shop...

I asked him to "reset the signal." He said "I don't know how to reset the signal; how do you do it?"

Finally he took it from me, opened the power-connector end (2 screws), poked around, muttered something ("Doesn't even have <something>," pushed something down and closed the cover again.

One bar...

My heart sank...

But I software reset it myself then (see steps above) - and this time after reboot the phone came back will full signal strength.

No charge for the repair - "I only remove two screws and plug it back in," the technician said. I did not ask him what he "plugged back in..." - but am all set now - till I drop it again...

so it seems to need both a SW and a HW nudge...
