Actual 4G hasn't even been ratified yet. All carriers offering its support are using whatever spectrum they have available, and not any recognized standard. This is why any Telstra 4G capable hardware is entirely incompatible with other carriers. I'd wait at least a year yet before trying to find suitable cross-carrier, cross-platform support.
My understanding is that there are about 23 different "4G" frequencies in use world wide. We've had issues with 3G hardware being good for one network or another network -- but now many newer phones offer quad band GSM and quad band UMTS (3G). I quoted "4G" because really, we only have HSPA+ variants and not true 4G anywhere here; the rest of the world is the same. Apple got themselves into hot water claiming 4G when in fact it is not -- that trouble was in EU and here in AU. At the end of the day, if you want to go with 4G or similar, then you need to know your broadband or other mobile device works on the right frequency for the particular network you want to connect to. Oh and Telstra 3G on 2100 is now very much in it's dying days.... they previously share the 2100 network with the Orange brand (which become Three brand of Hutchison Telecoms -- which is now Vodafone Hutchison Telecom). Optus still have 900/2100 but with their move to "4G" networks, we'll see more frequencies in play...
