Verizon's website says you can only use exchange with a corporate plan, which costs more. Can I get the lower personal plan and access exchange with the Droid X without Verizon forcing me to the more expensive plan?
Yes just go with the lower plan. I was able to access my school's Exchange account for e-mail just fine on my Droid Eris with the lower plan, so I don't see why you couldn't do the same with the DX.
