I got an iPhone about a week ago. I kept it in its OTB state for the past week, and I was  dissatisfied with what it produced. If you are not a big person for technology, then you’ll love this phone, if you a tech geek (like me), you might have a different opinion about it – Jailbreak it.

Jailbreaking:
“When you want to add ringtones, change wallpaper, or run third-party applications on your iPhone, you need to perform a task called “jailbreaking”. What this does is to open up your iPhone’s file system so it can be accessed from your computer. There are a number of tools available to jailbreak.”

I sync my iPhone to my PC, so I used iLiberty, worked great! Whatever you do don’t use ZiPhone!
