Each year we beat Apple’s brilliant iPhone, the new one. This year we finally have the features we wanted for some time, like the new , the front camera, flash light with the best quality and of a better screen. iPhone4 also includes a few goodies hidden inside, making it the best model to date. Is it worth upgrading to iPhone 3G? Just bought the iPhone 3G and not sure you should already be updated? Or do not have iPhone yet and believes that the iPhone could be moved to 4. Read on to find out if the iPhone can be four to live with their expectations.

then..how about design and constructions?

Apple iPhone 4 design improvements over previous versions, offering 3G. The new model is only 0.37 inches thick, compared with the predecessor of 0.48 inches.No plastic on the outside of 4 iPhones and deck is standard for all current iPhone is gone. The front and rear glass now. Apparently, the glass used “30 times harder than plastic,” and “proportional to the strength of sapphire,” according to Apple, Jonathan Ives.Between two sheets of aluminum strips of glass that wraps around the phone. The interesting thing is that the metal casing as an antenna for 3G, Wi-Fi, GPS and Bluetooth, a significant contribution to the signal is used.

And When looking at the iPhone screen 4, which was just beautiful. This is probably one of the best in the new model. The new screen resolution 960 x 640, 480 x 320 so far against all iPhone and iPod touch.Since the does not get bigger, there are more pixels per inch is now – 326 to be exact. Currently there are no other smartphones on the market with a screen resolution. To the eye, almost like a fingerprint. You really can not see the pixels re, and everything is fresh.4The Apple iPhone will be a matter of time until all applications currently being  updated to support the resolution. Developers have to do a little work to make this change.

And Now if the iPhone screen size, which would be a different story increase, but I see that happening soon.
