The iPhone has come a long way since 2007. Today, Apple introduced the 4th generation iPhone, dubbed the iPhone 4. iPhone 4 carries a service built right into the phone app called FaceTime that allows iPhone users to video chat. Although it is only over WiFi, it is understandable especially with AT&T’s cap on data at 2GB. The first thing you’ll notice about iPhone 4 is the new slick design.
There is aluminosilicate glass ( the same stuff used on windshields of helicopters and high-speed trains) on both the front and the back which makes it pretty tough and resistant against falls (no more broken screens). The backside of the phone has a 5 megapixel camera with flash (can also be used during FaceTime) and allows 720P HD video recording. The Retina Display pulls a 326 ppi screen instead of the previous generation’s 126 ppi. The is truly a step up, making video and pictures look stunning on the 3.5 inch multitouch display. iPhone 4′s components are held together by a alloy band that holds the antenna. The volume rocker is now separated into two different buttons and the silent switch got a metal makeover. iOS 4 is still the same except for the introduction of iMovie for iPhone (iTunes Link) and NetFlix (iTunes Link).
Safari 5 which was released a few hours ago doesn’t have many cosmetic changes, although it finally does get the ability for extensions and allows for developers to build custom extensions for it. It also receives Safari Reader which allows you to watch articles in a clutter free view, better HTML 5 support, a much faster experience and the Safari Development Program for developers to make new extensions.
Renamed from iPhone OS 4, the name was changed to prevent mix-ups with the name of the new iPhone 4. Full details for iOS4 are here.
**Note: iPhone 4 is available for $199 (16GB) and $299 (32GB) and iPhone 3GS as the lower end model for only $99.
