Although the CNet blog builds a pretty good case for why the new iPhone will replace RIM's BlackBerry as the mobile phone of choice in the business market, me thinks it boils down to three little letters why not -- AT&T.

For while it may claim reliability, there are more than a few places that get lousy reception from AT&T Wireless. Hence the reason to switch to Verizon (or even Sprint).

So until we have a little more democratic availability -- as in more than one wireless company offering the product, don't see it happening anytime soon.
