Can you make out going calls regardless no signal bars..? is it still in warranty/worth checking with Apple...,are you running any app that hides the signal bars..?

[willywonker2010]

if it under warentty take it
to apple
job done

[Jo-Jo]

no calls fail in and out and it's out of warranty with apple

[billy2]

is it the same sim card you got with the phone ??? all so have you tryed 3g off

Have you called your network to check if the IMEI has been blacklisted?

Just because you have not reported it doesn't mean a fcuk wit in a call centre didn't press the wrong buttons.

[Jo-Jo]

as i understand if its blacklisted it would state no service and not my carriers name

[johnboy1974]

jo jo i agree with canker it looks like its been blacklisted or could be a faulty sim card also. I had one that was blacklisted and carrier did show up but no reception bars.

have contacted vodafone this evening and it is not blacklisted .

[Canker_Canison]

Ok, do you have the all important rubber band around the side?

Has it been anywhere near water or have you handled it with wet hands?

I think it's going to be a trip to a repair shop. But depending on your answers & how brave you are, there may be things you can try.

The phone has not been unlocked? Have you had from new? Myself I would book a slot with the Genius bar and milk it for all it's worth... regardless the warranty has expired... Apple have been known to swap the iPhone for well known documented problems. you have nothing to lose.

I thought I was the only one! phheeww hehe..

Well same problem as you..

Iphone 4, unlocked at the phone shop where it was bought (Oh I live in Copenhagen, Denmark). I updated the iphone 4 through Itunes to IOS 4.3.5 BB 04.10.01 and there are no signal bars. The carrier (Telia DK) is found and 3G is available which mean I can surf on the net, check mail etc. but there are still no signal bars. Everything works except the phone and texting part because of no signal bars! not jailbroken btw! Tested with 3 different SIM cards from 3 different Carriers. Same issue.. Any suggestions?

Thanks.

They all sounds IMEI blocked to me

I had one on O2, that was IMEI blocked but O2 still showed. IMEI is blocked by Apple not your carrier, and they can't unblock it.

If anyone wants to sell any, give me a shout.

The very fact it was "unlocked" and you updated the BB through a firmware upgrade to 4.10 points to the problem.
