iPhone 3GS are more roundish and without Siri. The edges instead of being straight are round. The iPhone 4g has square edges without Siri. The iPhone 4S is just like the 4g instead it has Siri. The iPhone 5 is longer and has Siri. The iPhone (original) has round corners and is small. Same with the iPhone 2. If you have a iPhone or iPhone 2 you can replace them. Also, the iPhone 3gs is not out so you cannot buy it anymore. Only the 4, 4s and 5 are out. They will be getting rid of the iPhone 4 soon.
NO, the iPhone 3GS and 4 are differently shaped.
No. There is no such thing as an iPhone4g or an iPhone that works as a 4g phone. You either have and iPhone3Gs or the iPhone4, or the iPhone4s. None of them are 4G.

depends what you want to use it for if it's for business i would recomend the blackberry but if it's just for a phone i would recommend the iphone3GS I think the iphone 3G is cheaper than the iphone 3GS and you can get video on the iphone 3G not just on the 3GS however the iphone will not work as well as it in America is done by at&t which do not cover most of the country but will cover most of the east coast
