Q. i was going to get an iphone 3 but now i kind of want an iphone 4. but if there is really no big difference i will just get the iphone 3 since its cheaper.
A. New Features in iPhone 4
FaceTime
FaceTime is a video chat feature available in iPhone 4. This is the biggest feature (hardware and software) that the iPhone 4 has over the 3GS. At the time of launch, this feature is only supported over Wi-Fi and only if both parties are using an iPhone. Not only does FaceTime allow users to see each other while chatting, they can also "flip" the view from the front camera to the back camera so you can show the other person what you're seeing.
Software Features
The iPhone 4 operating system is called iOS 4. All older 3GS phones were eligible for an upgrade to this new operating system. All new iPhone 3GS phones are also shipped with iOS 4. So all new features should be available to iPhone 3GS except FaceTime, which relies on the front and back cameras. The important new features in iOS 4 include:
Multitasking with apps
Bing as a new search option
iBooks for the iPhone, which also supports reading PDF files
iAds are ads inside applications that are powered by Apple's advertising network. This provides an additional revenue stream to app developers.
[edit] Hardware Features
The iPhone 4 is 24% thinner than the iPhone 3GS. It has a glass body (both front and back) and a stainless steel rim that also functions as the antenna. The glass is about 30 times harder than plastic.
Retina Display
The iPhone 4 also has what Apple calls the "retina display". The iPhone 4 screen has 326 pixels per inch, which is more pixels than the human retina can see (when the device is held 10 to 12 inches from your face). The iPhone 4 screen is 960Ã640 pixels, giving it four times as many pixel as the iPhone 3GS. This higher number of pixels offer a higher resolution, making pictures and text on the screen sharper. The 800:1 contrast ratio is also four times better than the iPhone 3GS.
Faster A4 processor and Larger Battery
The iPhone 4 uses the A4 chip (the same processor used by the iPad) and a larger battery. These two factors have improved battery life by as much as 40% over iPhone 3GS for talk time.
Gyroscope
Another hardware addition in the iPhone 4 is the gyroscope, a device for measuring orientation. This will make new kinds of apps possible for the iPhone 4, such as enhanced game controllers similar to the Nintendo Wii.
Camera
The back camera on the iPhone 4 is 5 megapixels (compared to 3 megapixel in the 3GS model). The iPhone 4 can also record 720p HD video at 30 frames per second. The iPhone 4 also has a front camera, which the 3GS does not have. Apple's iMovie app for the iPhone costs $4.99 and will let users edit the videos they take on the iPhone.
Antenna Problems
When the iPhone 4 was released to the public on June 24, 2010, there was a spate of antenna problems caused by holding the phone in certain ways. Because the steel rim of the phone is its antenna, holding the phone when covering certain key areas of the rim resulted in dropped calls.

Can iphone4 screen protectors be used for iphone 3?
Q. When I say iphone 4 screen protectors, i mean the ones used for the front of the iphone4, not the back. So can it be used for iphone 3 as well?
A. The iPhone 4/4s is larger than the iPhone 3G/GS. You would need to trim the cover down to fit the iPhone 3G/GS.
Can a iPhone 4 GS flexible cover fit my iPhone 3 GS?
Q. I have the iPhone 3 and would like to buy this pretty Hello Kitty iPhone 4 GS cover for it. It is a flexible cover. Will it fit mine? (I don't want to spend the $17 plus shipping and handling, if it won't.) What do y'all think?
Thanks to everyone for answering. I asked this earlier and no one did. Thanks again.

A. It won't. The flexible ones may seem stretchy but it as you've realized, the iPhone 4 has sort of pointed corners and the iPhone 3 has rounded one. don't risk it. look up hello kitty iPhone 3 covers instead :)
