Using iPhone w/ Blackberry Data Plan

[haddman]

You can do it without jailbreaking or unlocking by changing the APN and it works fine. Just go to this site www.unlockit.co.nz and select the APN file for AT&T (wap.cingular). After that it should work fine on any AT&T data/blackberry plan.

I've tried doing it before but it didn't work. The APN switching might work.
