Hello I have a factory unlocked Iphone 4s and was working great for 5 months after purchase date running 6.1.2, and after I upgraded it to 6.1.3 it started to have signal issues to the point that says SIM is recognized but there is no bar of signal at all, dont even let me make any call nor receiving calls.

Here I attach the Screenshot:


I have been waiting for the IOS 7 since I understand that the main issue is the 6.1.3 for iphone 4s in some devices. Hopefully if I upgrade it when iOS 7 is available will work, oh, and by the way, I cant take it to the Apple, since its over warranty..


Have anyone experience this and have had the luck to solve it=??
