Hmmm, Vodacom also made some comments about using 800MHz in future.
Ideally, for SA, I believe that 800/1800/2100/2600 would be a good range. But it should be OK.
Actually 800Mhz/2600Mhz are probably going to be the standardised frequencies in most of the GSM world going forward (with some 1800 MHz for early adopters).
From that point, the iPhone and iPad aren't really future proof, but then no one buys tech for what it might do in a year.
