I value the ability to tether over unlimited data, of which I've never gone over 1.7 GB in a month.
The $60 I save per year can be re-allocated to 6GB of overage data or 3 months of tethering. Some months, I may even go further and downgrade to the $15 plan, esp if I'll be out of the country for part of a month...
I wish ATT would just charge $.01 per MB and be done with it there.
Aside from browsing, IM not going to download gigs of stuff over a slow 3G connection.
Yeah but the iPhone 4 can support up to 7.2 Mbps if AT&T actually gets around to supporting it
I tether my phone and can comfortably stream stuff off of Boxee.
