I just got a reply from Virgin Mobile's Customer Care. They will be releasing Sony Ericsson GC85 (GPRS+EDGE) data cards @ about R1300 (cash) in August! Have a look on SE's site:

Would've been nice if they would release the GC99 cards though. GC99 got UMTS/EDGE + Wifi.
I was a bit confused about UMTS so I googled around and found the following :
Technically generations are defined:
# 1G networks (NMT, C-Nets, AMPS, TACS) are considered to be the first analog cellular systems, which started early 1980s. There were radio telephone systems even before that.
# 2G networks (GSM, cdmaOne, DAMPS) are the first digital cellular systems launched early 1990s.
# 2.5G networks (GPRS, cdma2000 1x) are the enhanced versions of 2G networks with data rates up to about 144kbit/s.
# 3G networks (UMTS FDD and TDD, cdma2000 1x EVDO, cdma2000 3x, TD-SCDMA, Arib WCDMA, EDGE, IMT-2000 DECT) are the latest cellular networks that have data rates 384kbit/s and more.
# 4G is mainly a marketing buzzword at the moment. Some basic 4G research is being done, but no frequencies have been allocated. The Forth Generation could be ready for implementation around 2012.
