Hi there, I was wondering if anyone can help me with this problem: Recently, I realised that when I unlock my iphone at work (inside) to check out Safari, the Edge icon is on. The problem is, my coworker also has an iPhone with the same carrier and he has full bars with 3G. I found out that if I go to settings, turn 3G ON and OFF twice, it will eventually show the 3G icon. I wanted to know if anyone else is having similiar problems? Is there any way to fix it or do I have a defective phone? Thanks for your input!
