LCD: Apple has added a new type of display called the Retina display. With the Retina display, everything you see and do on iPhone 4 looks amazing. Text in books, web pages, and email is crisp at any size. Images in movies and photos are stunning at almost any angle. That’s because the Retina display’s pixel density is so high, your eye is unable to distinguish individual pixels. High resolution of 960 x 640, its absolutely fabulous.

 

Camera: The iPhone 4 has 2 built-in cameras for video calling. The back has been upgraded from 3-megapixel camera to a 5-megapixel with zoom and added auto focus feature. The tap zoom works pretty-well, the pictures comes out well. Flash is decent, not to impressed with it. Again it’s better then not having one. Also the most noticeable thing about the camera is faster shutter speeds. This helps for less steady hands, so your images don’t come out blurry.

 

Performance: Performance is a huge thing for the new iPhone. Right away you’ll notice a huge speed difference. Apps load up faster, multi-tasking is smooth and seamless. The iPhone is using the new A4 chip, same as the iPad. If you’ve played around with the iPad, you probably can guess how fast the iPhone 4 is.

 

SIM: The iPhone 4 uses a Micro-SIM instead of a regular size SIM card. For people who want to switch between other phones that use a regular size SIM card, you can purchase a Micro-SIM to SIM adapter off ebay. Just ordered mine, more details on that when it arrives . While on the call with AT&T for activation for my iPhone 4; I asked them what I’ll need to do, if I want to use my old 3G again. They said you won’t be able to use your old SIM card currently in your 3G, because once it is deactivated you can no longer reuse it and to purchase a new SIM from them ($25-$30).

 

 

Form Factor: The iPhone 4 as you can see is noticeably thinner then the 3G. The LCD screen is a little bit bigger. As for weight, it is heavier. I personally don’t mind it to much, but others might.

 

 

Buttons: The previous iPhone generations side buttons would become flush after using it so many times. It was a bad design, but this time around Apple has finally learned their lesson. They have separated the + & – controls.

 

 

All I have to say, this is an awesome concept. I realize that iPhone isn’t the first to have it, but It works really well, and the quality is pretty good. Then again, it does use WiFi only. AT&T most probably put restrictions on this, maybe because their network can’t handle it?

 

Issues:

 

The first thing I looked at was the reception issue that everyone was having. If you hold the iPhone in your left palm covering the bottom left corner of the phone, the reception should drop slowly and eventually giving you no service. This is indeed happening, I have tried it myself.

 

 

Reception dropping: I also noticed that bars would randomly drop from 5 to 3 just standing in one place.

 

Upgrading from 3G: Before using the new iPhone, I backed up my 3G and then had the iPhone 4 pick up the backup from the 3G. I wasn’t able to do FaceTime, and FaceTime option didn’t appear in the ‘Settings’. After reading though some iPhone forums, I found out that it’s a bug. And in order to get that option back, I had to restore and start fresh.
