You don't need to get the $30 package with the Blackberry. The iPhone has it tethered on no matter what. Don't listen to a rep that says you have to get the $30 package on the Blackberry...the only reason you need it is for the MIR, that's it.
Granted, I don't think there's much of a point to the PDA type phones without the package, but that's my personal opinion.
By the by, don't get the Storm. It's a piece of crap. You could always grab the Curve or the Pearl. But if you're going to shell out for the Bold, you might as well grab the iPhone, because the Bold costs 400 bucks.
