sort of offtopic..and er..on topic.
can someone expand on this 'personal hotspot'? i.e. if I have a 3G dataplan on my iphone then i can create some sort of 'wifi' zone for other devices to share that 3G? is that correct? and if so..would rogers/fido/telus charge extra for that capability even though it'll be built into the o/s.?
