There is no difference at all.
EVDO (Evolution Data Optimized) is a 3G (3rd generation) technology. It allows the user to access high speed internet over his mobile device on a CDMA network.
Hope this helps.
This is basically the speed of data for your cell phone. 1X will provide slightly faster speeds than dial-up where EVDO will provide DSL like speeds.
The 3G has 3G connection, and I believe it is a little faster too.

The iPhone 2G is much slower than the iPhone 3G.
3G is 3rd generation mobile technology. UMTS is one of the technologies under 3G, just like CDMA2000.
3G has better memory and faster internet. The higher the G the better. This is reffering to an Iphone.
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 BTS is greater than 2g bts. and it is with new technologies.
The difference between and 3g and 4g map coverage is the amount of memory that each contain. Obviously, 4g contains a lot more memory. 1g is in fact, a large difference.
4g is newer updated and much faster than the old 3g network trust me theres a big difference.
