The iphone 3g is the third generation iphone , is that what you are asking
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.
2g is 2nd generation 3g is 3rd generation
iPhone 3g is capable of 3g access, but not iPhone 1st generation. However, some areas do not have 3g coverage, so iPhone will automatically switch to EDGE. iPhone 1st generation only has EDGE and Wifi, and iPhone 3g has EDGE, 3g, and WIFI.
Yes, the iPhone 3G/3GS is thicker than the iPhone (first generation) at its thickest point. The iPhone 3G/3GS is 12.3mm while the iPhone (first generation) is 11.6mm. However, the iPhone 3G/3GS has a tapered back, and has roughly the same overall volume as its predecessor.
The iPhone 2G does not have the hardware to capture a 3G signal. It does not matter where you are.
Third (3G)
There is a small chance you have no enabled 3G. To do this follow these steps. Go to Settings > General > Network and Enable 3G should be set to on. Also your area may not have 3G capabilities. In this case there is no 3G signal for 3G to work. To check 3G coverage contact your provider. Also if your iPhone is a 1st Generation and not the iPhone 3G you do not have 3G capabilities.
iPhone 1st generation does not have built in GPS, but iPhone 3g has a built in GPS module. However, when GPS is not available, iPhone 3g will also use cell towers to triangulate your approximate location.
An individual is able to purchase an iPhone 3G through websites such as eBay and Amazon. This generation of iPhone cases can also be purchased at RadioShack and perhaps during the summertime, garage sales.
Yes you can but you will not get the benefit of the 3G network speed, you will only get EDGE. Also this will require an iPhone data plan change and if you had the unlimited plan on the iPhone 3Gs you will lose it and you will not be able to get it back.
