Why would I deactivate them if I was assured that an iPod Touch 3G would never happen?I have them activated now because there is no 3G iPod Touch and an iPad is too big.
If AT&T has you on the hook for 3 iPhone contracts now, why would they ever want to give you iPad style data on an iPhone style device?
I think that AT&T would actually appreciate having an increased number of customers with data plans overall. Sure they may lose some people with iPhones, but it'll probably be more than balanced out by new uptake of iPod touch 3g owners.
Remember when that AT&T person said that most iPads would be wifi only? Remember when AT&T abolished the unlimited 3G for $29.99 for iPad? Somehow I doubt that the telecoms want more data hungry devices and users on their network that aren't roped into expensive contracts.
