İmage Quality
Obviously affects me when I saw for the first time a new frame or not the shape of the first, was the brightness of the screen and vitality. Steve Jobs first announced the concept of Retina Display on iPhone 4, you can tell a lie I thought a little bit exaggerated. However, I saw a drastic improvement compare it with the iPhone 3GS. 960 × 640 resolution and 326 ppi (pixels per inch) value of the air brought to the screen in a different iPhone 4's for sure.
As in the photo above, the iPhone 4 and iPhone 3GS screens side by side, compare, this difference is already clearly visible.
Speed
iPhone 4, 3GS compared to the other immediately noticeable difference is the speed. iPhone 4 is the applications / pages opening faster than loading 3GS. However, the difference in speed on every new device we use in examination of the application Speedtest.Net appeared.
Note: The above speed test, using the 3G internet connection, an interval of one minute were in the same environment.
Apple has limited its older iPhone models 3G internet connection upload'ı. For example, users of the iPhone 3GS, 3G connection when they want to do an upload speed could see the value of the maximum of 384Kbps. But the above results, given the upload speed of the iPhone 4 is no longer seems to be no limit.
Antenna Problem?
This is a lot written in the press last week, incidentally, and some users complain about the iPhone 4 antenna issue on which I want to share observations confirmed. But this is not an issue for those who do not need to explain briefly the iPhone 4 Due to the metal frame as an antenna, the device is touched certain points of the frame-up problems happening. Especially a lot of devices that use unshielded number of users seems to suffer from this problem.
I tried my friend's device, but I too have encountered such a problem and the context, in spite of bırakmamama untouched. Even during the speed test, such as the photo above that I've come into contact at various points in the frame, but the problem did not appear. This problem no longer occurs in some devices, too, frankly, I do not know if something wrong with the software, but there's nothing to worry about as it seems. Of course, for some time to tamper with the device, you really need to wait to see if there is a problem.
Applications
Concerns about the iPhone 4 is also an issue with how it looks in applications not intended by 960x64o'a. iPhone 4 does not have a special design to afford many very uncomfortable when I test the application will obviously have not encountered a situation.
For example, the Facebook application for iPhone 4 screenshot above, that is fine, I guess. Of course, the iPhone 4 still had the chance to test an application specially designed. After examining the idea of such an application screens may vary.
