iPhone4

This gadget is already available in store and maybe some of you guys may have it in your pocket. But it is ok for you to have one as I want to review this new generation of iPhone. From looks it seems that this new phone is industrial made, with glass and stainless steel, it looks glossy and it may make you adore holding it. But bear in mind, the position of your hand when you hold this phone as it will reduce the signal strength of your phone. The drop in signal strength only seemed to occur when we held the phone in our left hand, with the bottom of our palm slightly covering the bottom-left corner of the phone. Some says that the steel band around the phone that led to it. No worries, Apple introduce to you a so-called Jumper to solve this (see below).

Bumpers for iPhone 4

Dress up your iPhone 4 with a Bumper. Choose one of six colors — white, black, blue, green, orange, or pink — and slip it around the edge of your iPhone 4. With metal buttons for volume and power, two-tone colors, and a combination of rubber and molded plastic, Bumpers add a touch of style to any iPhone 4.

Retina Displays

by developing pixels a mere 78 micrometers wide, Apple engineers were able to pack four times the number of pixels into the same 3.5-inch (diagonal) screen found on earlier iPhone models. The resulting pixel density of iPhone 4 — 326 pixels per inch — makes text and graphics look smooth and continuous at any size.





Facetime

People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With just a tap, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 or to the new iPod touch over Wi-Fi. And it works right out of the box. No other phone makes staying in touch this much fun.



Here is the review



Pro: Retina displays, Facetime, Apps well known, fast, simple multitask function, long battery life

Cons: Video calling that only works between iPhone 4 handsets over Wi-Fi, Signal drops when you hold the phone in a certain way, Doesn't feel as thin as it is, Expensive, Tied to iTunes software,



Conclusion: iPhone is not a phone that you like to drop it.
