Yes,but it costs $600 for the upgrade fee..my sugestion is that you just cancel your current iphone contract for $150,and get a iPhone 4 for $200 plus the activation fee,and you will have a iphone 4 for $350 instead of $600!
No, Apple only makes the 3GS, 4, and 4S.
iPhone 3G and 4(no G) are types of iPhones. If you've been with AT&T for more than a year you can go into an AT&T store an upgrade your plan for two more years and get the iPhone 4 for $200 plus tax.
Iphone 4 cases are not compatible with 3g iphones because the newer iphone is not made like the 3g. They have different bodies are are much more angular that the 3g.
The difference you will see between the iphone 3G/3G S and the iPhone 4 is quite noticable. Especially the design. AS for the iphone 3G,there is no recently used apps bar (multi-tasking), you can't have a background wallpaper on the homescreen. As for the 3G S, you have both of these features. However, the iphone 4 has the Retina display, which the previous models do not. The iphone 4 has facetime (video calling), which the previous model does not. The iphone 4 can do HD video recording, has 5.0 MP with flash. I believe the 3G does 2.0? and the 3G S has 3.0 MP to it. No flash on previous models. Really, you can just go to the iphone section and i'm sure you can compare between the iphone 4 and the 3G S. In US, they do still sell the 3G S model but in 8 GB of storage, each country could be different where they could still sell the 16 GB model or the 32 GB, but very unlikely, unless they have few in stock. iphone 4 comes with either 16 GB or a 32 GB.
iPhone 3GS. Then the iPhone 4 and then the iPhone 4S.
It is the 4th model of iPhone. But iPhone generations do not go from one up: 1. iPhone 2. iPhone 3G (because of 3G connection) 3. iPhone 3GS 4. iPhone 4. 5. iPhone 4S
The iPhone 3G can be found free if you sign a contract with any big cell company. Because, the iPhone 4 is the model everyone wants you can get the first generation iPhone for cheap.
If you've been with AT&T for atleast a year it will cost you $200 and a two year contract.
Yes
If you just recently got a new iPhone 4, connect it to iTunes and iTunes will identify it as a new phone. If you have previously synced your iPhone 3G with that computer before, then iTunes should give you the option to sync the new iPhone with a backup from your latest iPhone 3G sync. When you do that, your files from your 3G will be transferred to your iPhone 4. Hope that helps :)
I have a 3G iphone with ios 4 and it didn't work on it
No it is not as sliim as iphone 3g
