The 3G has 3G connection, and I believe it is a little faster too.
The iPhone 2G is much slower than the iPhone 3G.
2g is 2nd generation 3g is 3rd generation
2g is 2nd generation 3g is 3rd generation. 3g is much faster. iPhone 3G can support WCDMA and HSDPA frequencies, but the iPhone can't.
You get faster internet then the original iPhone.
iPhone 3G hasa different shapethe ability to download appsbetter Safariandis cheaperis more user friendlycomes in 2 colorsis faster.
3G has better memory and faster internet. The higher the G the better. This is reffering to an Iphone.
An iPhone 4g has better technology. It also includes SIRI, who answers all questions. Furthermore, the iPhone 4 has the capability to operate on the 4g network, whereas the iPhone 3g does not.
The only difference is the network that it runs. The 2G iPhone is slower when you are browsing the internet, while the 3G has a faster network. Also, the iPhone 3G has more of a 'slimmer' feel to it, though technically slightly thicker. Other than that, there is no major differences, and they both run the same software.
The 3G S has more features like voice recognition, a compass, video recording (with a 3 megapixel camera) and a GPS. You can also stream movies and TV shows straight to your phone in areas that have wireless internet. For more info got to www.apple.com and click on a iPhone
It most certainly does. The only difference between 3G and 3GS is the processor speed and software. ALL accessories are interchangeable.
They are both very close in size with the iPhone 3G having a rounded back. There is no obvious size difference, however.
There is no difference in VISUAL size between the two. The difference is the gigs. Each gig has one milion bites of memory and so the iPhone 2g has two million bites of memory and the iPhone 3g has three million bites of memory. It sounds pretty complex, I guess you could say, but it really isn't.
