Hi all,

I have had my new iPhone 4 for close to 4 weeks now and everything has been a breeze until recently. My phone seems to show that the phone has "No Sim Card Installed" which is obviously not the case.

I have read online that the iPhone has some cases of 'shorting out' with the sim card tray coming in contact with the metal framework. Could this be the case?

I have taken the phone into my provider (optus) and they have issued me a new sim card and if the problem persists they will send it away and claim it on manufatures warranty.

Has anyone else had this issue and are they any suggestions on what I should do?

Thank You
