Skype is Free on all iPhone's!
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.
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
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 :)

The iPhone 3G is capable of accessing a 3G network. Some of the older iPhones and the new iPhone 4 can not access a 3G network, however. There are many droid that have the same applications as the iPhone but that will hook up to the 3G network.
iphone 4 definetely
Original Answer by Norfalka2545 Edited by Arianna Lovendino The answer is iPhone 4, because 3G is an advanced cellular network. If it were named "iPhone 4G", people may mistake the device for an iPhone 4G, when it is really an iPhone 3G. Hence, iPhone 4.
