I have an iphone 3g. Some time ago I went to a storefront business that advertised to unlock and jailbreak my iphone and they did. I now notice that when I click my home button twice the camera opens up to a point where I can take a picture. I know that when I do the same thing on my iphone 4 it opens up a reveals apps that are running and enables me to delete them {the camera does not open up as it does in the iphone 3g}. My question is: Is this a normal way for my iphone 3g to act?
