Well, this is a nice surprise.
Those of you with iPhones will know that Apple sometimes rejects useful applications because they perform (or out perform) a similar feature or application offered by Apple on the iPhone. When Opera submitted the Opera Mini iPhone application, the company recognized the fact that Apple had yet to let a third party browser on the iPhone with a timer. Today, Apple approved the application and right now, it's available for download via the App Store.
So what's different about Opera Mini and how does it compare to Safari? Opera says that due to server-side rendering, Opera Mini compresses data by up to 90 percent before sending it to the phone, resulting in rapid page loading with less data transferred. This is something the folks with capped data plans, especially when roaming, will appreciate. It also means if you're on EDGE or your 3G is really weak, then you'll get a better browsing experience with Opera Mini.

Check out the video below for a demonstration of how much faster Opera Mini is compared to Safari when the user is on a 2G EDGE connection.
