Hi chaps,
After some iPhone guru advice. My shinny new 4s is having problems, when I am at work it constantly drops signal. I put my sim back in my iPhone 3G and all is well.
However my new iPhone works fine at home and everywhere else just not at work? So the problem is with my new phone at one location.
Reading in the net a few threads recommend upgrading to 9A406 firmware?
Has anyone else had this problem or upgraded to 9A406?
