So I got the new iPhone 4s. I came from the iPhone 4, so the upgrade isn’t as significant like the previous upgrade. Many of the changes were either internal or software based. The form factor is identical to the iPhone 4 so those looking to get a new design will need to wait another year. There are quite a few features in the new phone. Hardware-wise the phone is noticeably quicker in video games, browsing websites, and when snapping photos. The performance improvements won’t be noticed by many, but it’s there.
On the software side the new iOS 5 added many great features. Some of the features that really stood out were the implementations of iCloud. Upgrading from my 4 to 4S was incredibly easy. You just login with your iTunes account and let iCloud do the rest. The whole process will copy all your apps and settings to your new phone. The other feature that was long over due were the revamped notifications. Apple clearly ripped it off Android, but I’m not going to complain. It’s a great needed feature and it works well. The app that many have been talking about is Siri. It’s a voice command assistant app that is built into iOS and is only available for the iPhone 4S. At first, it was fun to play around with, but I don’t see it as a necessary application for the phone, at least at this time.
Overall, the new iPhone 4S is a great device. Apple has decided to take the conservative update path on this new phone, so if you already have the 4, I don’t believe it’s a worthy upgrade to spend more money on — but if you have any of the previous phones, such as the 3Gs or below, it is a recommended upgrade.
