Just after the iPhone OS 3.0 was released I was waiting to upgrade to iPhone OS 3.0 until it could be “easily Jailbroken” (see “Need for Speed II“). Well, I couldn’t wait. Within two days I had upgraded my iPhone to OS 3.0 then Jailbroke it almost as soon as the iPhone Dev Team released their “redsn0w” multi-platform Jailbreak utility. The main cost of being on the bleeding edge was discovering first hand a number of apps which were not iPhone 3.0 OS compatible.

But enough about Jailbreaking. I’ve been using the iPhone OS 3.0 for over a week now, and I like it.

One of the new features of the iPhone OS 3.0 is that you now have more pages for Apps. It looks like it has been increased to 11 pages (or “Homescreens”). Now instead of a maximum of 148 Apps, the max is 180 Apps, although I have heard that this is affected by available (storage) memory. This is great, because now there are more pages for me to try to group my apps more logically, the most used ones on the first couple of pages, eBook and reader type apps on one page, games grouped together over two pages and other apps after that.

The new landscape keyboard also really does make a difference, and is much more conducive to “Thumb- typing”, with my typing speed considerably faster than in portrait mode.

At the everythingicafe forum, members came up with this list of the more than 100 changes in the iPhone 3.0 OS and iPhone 3G S.
