What is 3G? What is 4G? Come to thing of it, what is a G and how many of them do I really need? Andy and Sean explain the difference between the different types of 3G and 4G data networks, with the help of a bunch of melons.

The last time we used melons was in Trojan Horses Demystified episode 95

Wikipedia - High-Speed Packet Access for GSM
Data network access technology for GSM phones. You might also hear HSUPA, or High-Speed Uplink Packet Access. It's incrementally better than HSDPA with less lag/latency.

Apple iPhone 3G introduced data connections using EDGE at 384 kbps, and HSPA at 3.6 Mbps. HSDPA is actually a subset of HSPA so I should say HSPA+ here not HSDPA+. Many parts of the world outside of Canada and the United States are already there at HSPA 21 Mbps.
