iOS4 and Beyond
When most people think of an iPhone update they think of the large scale iPhone updates, such as the update to iPhone 3.0. iOS4 has been the most recent large scale iPhone update to bring in fundamentally new features to the firmware such as multitasking and more iPhone wallpaper image options. Apple is not sitting on the success of the iOS4 update, which came out along with the iPhone 4 release. Instead Apple continues to build on iOS4, releasing more iPhone updates that just add to this. Here is a look at the iOS 4.0.1, the latest iPhone update.

Updating to iOS 4.0.1
You have quite a few options on how to update to iOS 4.0.1 on your iPhone. If you simply plug in your iPhone to your computer it is very likely that it will recognize that the iOS 4.0.1 update is available for your iPhone and then ask if you want to initiate the update. If it doesn't, you can manually select to update your iPhone. Once your iPhone is plugged in to your computer select it from under the Devices heading in the left hand column of your iTunes player. Once in your iPhone go ahead and look in the Summary tab, and under the Version heading there will be an update button. Go ahead and hit the Update button and you will have a pop up menu that will inform you that you are now going to download the iOS 4.0.1 update for
your iPhone. This will be followed by a screen giving relevant information about the software update, and after you hit next, you will be asked to agree with the Software License Agreement. Once you finish with this, then iTunes will begin downloading the iPhone software update, which will take five or six minutes. After it is done the software will be extracted and iTunes will begin backing up your iPhone. This will then "prepare your iPhone for update," which
restarts it and then feeds the new software to it over a couple of minutes. After this your iPhone will restart, reappear in your iTunes, and will be ready to use.

Why iOS 4.0.1
The iOS 4.0.1 update will work on the iPhone 4, the iPhone 3GS, as well as the iPhone 3G. The earliest version of the iPhone has been left behind by this update, as it was with iOS 4. The main reason for the release of the iOS 4.0.1 so quickly after the release of iOS 4 have been the dramatic problems surrounding the iPhone 4. The iPhone 4 has had signal reception and dropped call issues surrounding the position of the antenna, and the display listing how many bars of service you may have at a given time has not always been accurate with iPhone 4s on iOS 4. To remedy part of this problem Apple rushed out the iOS 4.0.1 update, but it is relevant and useful to all iPhone users that have the option of this update. If you are using an iPhone 3Gs or iPhone 3G the update should still be performed, but iPhone 4 users must make this their top priority until the iPhone 5 comes out.
