No service on iphone4?

Seems loads of people are having this problem. I have found the easiest and non-technical fix in the world. This worked straight away for me. The aerial for the iphone 4 seems to be located on the bottom left corner of the phone. Simply hold the iphone in your right hand so that the left bottom corner is uncovered and voila, you will have signal. I know it sounds ridiculous but it seriously worked for me. I have tested it and if I hold the phone with my left hand (so my the bottom left corner sits in my palm) I get 'No service'. Hope this works for you too.
