Apple's sixth-generation iPhone 5 is here, with the first slew of reviews overwhelmingly positive of the new iOS 6-powered smartphone. It seems that everyone has fallen in love with the iPhone 5, praising its lightweight, thinner feel, and super-fast speed.

The new 4-inch screen is loved, but apps have to be redone to work with the extra height. If app doesn't support the iPhone 5s larger, 4-inch screen, the apps will sport black bars at the top and bottom of the app, something reviewers point out. Here are some of the reviews:

Image quality is still among the best out there for a cameraphone, unimproved but quite impressive in varying conditions. What has improved, though, is the speed. Tap that big ol' thumb as quick as you can and the iPhone 5 will keep up, whereas the iPhone 4S eventually fell behind. It's at least on par with the Galaxy Nexus, which also has a ridiculously quick shooter.

I found the new iPhone screen much easier to hold and manipulate than its larger rivals and preferred it. In my view, Apple's approach makes the phone far more comfortable to use, especially one-handed.

It's the same iPhone, but it's completely different. That's the main takeaway point for the iPhone 5′s design. It's something you can't really appreciate until you get up close and personal with the new phone, but when you do, wow, you'll really notice that difference.

The iPhone 5 is the iPhone we've wanted since 2010, adding long-overdue upgrades like a larger screen and faster 4G LTE in a razor-sharp new design. This is the iPhone, rebooted.
