I have Iburst. They have bad manners and an awful phone service which one day even asked me what the company did!
The device is terriffic and runs off the pc's power not a separate supply however it has very limited reach. Yesterday I checked out the cdma from tls which has 98% of Australia. Iburst works in only a few areas and not for example on the northern beaches, places in the West and Eastern suburbs etc.

I'd use the tls. in fact I think i'll take the loss on buying the iburst modem and switch. Good where it works but very limited this iburst.
