It can be hard to distinguish a fake iPhone from the outside, but software-wise its not so hard.
Look for the App Store and iTunes Store, as well as Safari. That should tell you. If the icons and text underneath them are the same, chances are its a genuine Apple iPhone.
You have a really similar username lol. even confuses me. I like the avatar btw.
The Storm is pretty, I remember Blackberrys being butt-ugly, handset and interface wise. I doubt they would have ever concieved this design if the iPhone hadn't been around
