I am on a prepaid plan and I only use a few minutes every month. I would like to get a smartphone and a cheap data plan so that I could use the Maps app when I am on the road. I plan to get the Virgin Canada $10 a month for 100 MB data plan. I also want to be able to use Navfree (a GPS app) when I travel abroad. Given the limited use I plan to make of the phone would it matters if it is less powerfull than the 4 or 4S?
