first of all, its not hard to understand, you'll just have to imagine how data flows in the air, in what way, and how fast.
1G is the first generation celullar network that existed in 1980s. It transfer data (only voice) in analog wave, it has limitation because there are no encryption, the sound quality is poor and the speed of transfer is only at 9.6kbps. IT IS STILL IN USE in some country by police, taxi cabs, telephone company.
2G is the second one, improved by introducing the concept of digital modulation- which means converting the voice(only) into digital code(in your phone) and then into analog signals(imagine that it flys in the air). Being digital, they overcame some of the limitations of 1G, such as it omits the radio power from handsets making life more healthier, and it has enhanced privacy
There are 2.5G, which is a transition of 2G and 3G. In 2.5G, the most popular services is the SMS (short messaging service). Of course there are something else like GPRS, EDGE, High Speed Circuit switched data, and more.
For 3G, imagine 2000+kpbs data rates, its not only voice and simple data(message) that be transmit, services such as downloading, video calls, mobile TV, mobile internet are available.
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.
an easy way to tell is the second gen has 8gb and doesn't have 16gb and the 3rd has16gb but not 8gh
2g and 3g spectrum scam

The iPhone 2G is much slower than the iPhone 3G.
You will have to contact Airtel to convert your 2G phone to 3G. The same sim card can be used for both 2G and 3G, so you will not need to change to a new card.

Unfortunately, you cannot. Tracfone disables any unlocking of any of their SIM cards of any kind on any network, and you may or may not be penalized if you try. I suggest you unlock the Iphone 2G with T-Mobile, if you want lower-price service. I've heard THAT unlocking process is possible.
3g BTS is greater than 2g bts. and it is with new technologies.
