IPHONE 4s call failed??!!!

It's a hardware antenna design flaw I don't think any software update will ever fix it. Lets hope the iPhone 5 is a lot better!

I too am having the same problem.

Samsung GalaxyS III perhaps? It's really been tempting me....

Hi xDonx,

Could you please tell me how did you downgrade your phome firmware,

Much appriciated,

I have an iPhone 4S on 6.0.1 And I'm still receiving the same problem

My 16gb iPhone 4S keeps failing my **** calls. I even reseted my network settings and it worked for a bit but it is still happening. I NEED HELP. I even updated my phone to 6.01. WTH HELP

wait whay? i have tried everything to fix this. ITs very annoying. How do you fix?

I have had this issue with my iPhone 3G, my iPhone 4 and still with my iPhone 5. So, I'll hope Apple will fix this issue. It's very anoying...

Your solution worked for me. Before, I tried to restore my iPhone 4.

Thanks.
