What's more, if you invest in the new iPhone 4. We try to make a list of what it can and can not, so we can weigh for and against and decide whether to make the investment.

Let's start with the benefits:

1) It's the first iPhone with two cameras one at the front and one rear which allows video calling. 2) The camera has been upgraded from 3 to 5 megapixels and an LED flash has come on. 3) The camera can now record HD video (720p / 30fps) 4) The screen resolution has improved for 960 x 640 pixels, which allows it to display HD. 5) Made of reinforced materials, a glass material that should be 30 times as strong as / harder than plastic, the frame is stainless steel and works simultaneously as an antenna. 6) The battery is bigger and is now ready for 7 hours of talk time. 7) New processor (A4) can be connected to 802.11 n-network, built-in gyroscope and two microphones for noise reduction. 8) Can run multiple applications simultaneously (multitasking). 9) Video editing takes place on the phone (iMovie).

Disadvantages (the negative, according to temperament).

1) Up to now, video calling can only be done over wifi and only between iPhone 4 phones. 2) The storage is only 16 or 32 GB and can not be expanded. 3) The design is more square than the earlier, perhaps more nokia-like. 4) IPhone 4 and not 4G because it is not ready to use 4G. 5) With regard to the camera, it might be better, especially if compared to other brands at the same level. 6) The screen resolution is high / good, but the screen (3.5 ") could be larger. 7) Missing TV output. So it's up to you, whether you want to invest / upgrade, we immediately believe that the benefits win over the disadvantages, but it's a matter of temper.
