The 73Mbps speeds are a vast improvement over previous models, though questions remain on whether South African users will be able to experience the LTE feature of the iPad 3.
There is very little chance of any operator being in a position to use the 700 MHz or 2100 MHz bands for LTE.
As was pointed out, 700 MHz is not yet even under consideration as a digital dividend (changing from broadcasting to telecoms) in South Africa. The band was identified by the ITU WRC-12 conference in January as such a band in Radio Region 1 (Europe, Middle East, Africa), but the earliest that this would be realistic here would be 2015 anyway.
2100 MHz is in use for 3G (UMTS / HSPA) by four of South Africa's mobile operators (Vodacom, MTN, Cell C and 8.ta), and there's simply no room to use it for LTE, except perhaps in some rural areas. Vodacom and MTN are struggling even to trial LTE in 1800 MHz, by shutting down some GSM (2G) sites in these bands, forcing users onto 900 MHz (GSM) or 2100 MHz (UMTS).
Hence, the most likely scenario would seem to be that the iPad 4 (newer iPad?) will support the LTE bands that will be popular in Europe and Africa (800 MHz, 2600 MHz and 1800 MHz), in time for the launch of LTE services in many of these markets (seems like 2013/14 currently).
There are actually two models of the new iPad - the one in table is the "AT&T" iPad. The other model is the "Verizon" iPad, which has 700 MHz LTE, as well as 800/1900 MHz CDMA (which would work in this country on Neotel's network, in principle). This is probably the last Apple device that will have these variants, since the chipsets currently being developed (by Qualcomm and others) are rapidly approaching one chipset for all available standards and bands. The real challenge with all these bands is going to be antenna design, something Apple is careful about nowadays.
