Guam - It's finally here, the answer and the reason upgrading to the iPhone 4 is unnecessary. Wait, it gets even better, the OS download isn't just for iPhone users, if you have any Apple touch-based product, like the iTouch and iPad you're going to want to download iOS4, as well.
If your an iPhone user, your device can now pair with any Bluetooth keyboard. By connecting your iPhone to a Bluetooth keyboard, you'll be able to blast through piles of emails and even write modest reports without carrying your notebook around. For many road warriors who don't want to shell out for a netbook or an iPad in addition to the $200-$300 phone that they were going to buy anyway, that's a hugely-valuable feature.
Who would've thought using the iPhone could get any better than that?
With iOS, you can take all the apps on your iPhone and group them into folders for games, movies, songs and pictures to name a few, so go ahead and get organized, it definitely works for me and I've got over 55 apps on my iPhone.
All you need to do is hook you iPhone or iTouch up to your computer and open up iTunes. Click on the iPhone icon and then click the button that says check for updates. It should start downloading automatically, but if it doesn't you can also download the update at.
The update will take at least an hour to download, optimize and install the iOS, so if you've got some spare time on your hands, download the update now and trust me, it'll only get better from there.
