I am upgrading to a 32GB iPhone 3GS from my 4GB first gen iPhone. I am on a Family Plan that includes Unlimited Texting. As of right now, I am paying for the standard $20.00 data plan and nothing else on my iPhone. When I preordered my 32GB iPhone 3GS from Apple.com, there was no option to add a texting plan. Only the data plan was offered. My question is, does the unlimited texting plan still apply to my iPhone like it does now with my first gen iPhone? Also, is there an extra monthly fee to enable GPS on the iPhone 3GS?
