I’ve had the 3.0 Firmware installed on my iPod Touch for a few days. Even though it cost about $10 to download (for iPod users, it’s free for iPhone users) it was definitely worth it. Other than the new features it brings, I have noticed a major improvement in speed.
As for new features, it has a few that I really like. One is the Spotlight search. To get to this, you simply swipe left on the home screen, or hit the home button. Once you start typing in something you want to find, it searches through apps, contacts, music, emails, and pretty much everything.
Now there are Push Notifications. Push Notifications are basically when an app sends information to you even if its not running, for example, an IM client could notify you when you have a new IM when it’s not running.
If there’s anything I missed, let me know in the comments and I’ll make a new blog post for it.
