To jailbreak an iPhone 4 you need to download redsn0w. For better info go to youtube and search ' how to jailbreak iPhone 4 on (whatever your OS is .example: IOS 5).'
Ya you can jailbreak most ios firmware except 4-3-4 & 4-3-5 & 5-0

iphone 5
Yes, the iPhone 5 is lighter than the iPhone 4. The iPhone 5 weighs 3.95 ounces (112 grams), while the iPhone 4 weighs 4.8 ounces (137 grams).
Well it was said that the iPhone 5 would have a much thinner screen then the iPhone 4. Then the Iphone 5 would have more and better apps on it.
iPhone 4S
iPhone 4S
wait for iphone 5 and then get a 4 because they will be much cheaper
Wait! 5 will be awesome and 4 is...a 4.
When you are at the lock screen, follow the "slide to unlock" message by sliding the screen to the right. Then input your passcode.
nothing. it'll just be suddenly less appealing to people who have iphone 4 and they rush to buy iphone 5.
