Wat's Wrong with Apple Factory they actting like we are blackbeary users wake up it's ur Producte

we could go to court for that error i think error coming from bootrom that's fixed after week 26 so plz every body see if third serialnumber in ur phone is 9 then this is old bootrom they must fixs IOS 5.0.1 for old bootrom or tell us what's going on we must get answer from Apple we r not yaping

Great thanks for that worked for me first time

Mine is doing the same thing

I too am having similar issues and am very frustrated with this...it interferes with serious work I do with homeless teenagers to have a call dropped with a message that sim is undectectable and not be able to connect back with them. I'm going to address this to the media and see if they can shed some light if Apple chooses not to fix this problem.

I just upgraded my Iphone and now it needs to be activated AGAIN! It can't detect my sim card or other sim cards inserted in it! And it can't be activated without a sim card. What should be done? Do I need to bring it to the iStore and get it fixed or what? Anybody know what to do? APPLE PLEASE FIX THIS CRAP :/
