3G is the 3rd generation of mobile telecommunications data protocols. Two of the main 3G technologies are the HSPA family of protocols, and EVDO. HSPA is used by GSM networks such at AT&T, while EVDO is used by CDMA networks such as Verizon and Sprint. Current BlackBerries on GSM networks use EDGE, which is considered a 2.5G network.

EDGE is slower, and cannot handle data at the same time as GSM voice communication. So when you are talking on the phone, data stops. HSPA and EVDO can handle data at the same time as voice communication, so you can do things like get mail and browse all while talking on the phone.

As far as data speeds, the HSPA family of protocols are faster than EVDO, and with AT&T completing the upgrade of their HSPA network at the end of June, will leave EVDO in the dust. Technologically speaking, EVDO cannot compete with HSPA in max throughput.
