Has anyone else been having problems with the invalid sim message?? This has been going on for over two weeks now and it's causing me so many problems. Tried the usual rebooting resetting my 4s even done a complete wipe out and its got worse. I'm losing business now as customers are getting my answer phone instead of me as I'm having to reboot my phone every half an hour. Got phone in november
Please reply ASAP as getting really frustrated over this problem and orange just don't want to know
