2G is GSM whereby each user has a defined time slot to access the base station whereas in 2.5G, also known as GPRS, it is the aggregation of time slots to create a data packet for a user. GPRS is the first step towards a mobile data service.

The iPhone 2G is much slower than the iPhone 3G.
3g BTS is greater than 2g bts. and it is with new technologies.
2G means the device has 2 gigabytes of storage. 2KB means the device has 2 kilobytes of storage.
A regular SIM card comes with 32KB of onSIM memory which was sufficient to manipulate data on 2G network. but a 3G SIM card has 128KB of onSIM memory which is beneficial to handle high speed dat access just like more cache memory helps in faster processing. Otherwise there is no other difference between a 2G and a 3G SIM card.
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.
3G has better memory and faster internet. The higher the G the better. This is reffering to an Iphone.
1G is based on frequency modulation,analog technology,TDMA 2G is based on digital technology,FDMA 3G is based on CDMA which is a faster internet access source
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.
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.
