No signal and weak gps after drop


Last week I dropped my 3GS and immediately afterwards I noticed that it said "No signal", no matter what...

I also noticed that the gps signal is also extremely weak now.

I have already opened it and checked all the ribbons etc and I can't see anything wrong ? Anybody has some ideas ?

Kind regards

If the gsm is poor try swapping the dock connector or checking gold prongs are on metal frame from connector 7

It always says "No signal" and it keeps on trying.

I have swapped the dock connector and the gold prongs are also fine.

Any other ideas ?


Have you tried removing and cleaning sim? Should have thought of that first... Sorry. Try hard reset hold power and home until apple appears then release buttons and allow to reboot.


I did clean it and I have also tried another sim card. Hard reset also doesn't work.

Any other ideas ? Thank you very much !
