Any Inland Empire users on Sprint / 4s? Spend an awful lot of time on the 60, 15, 215 freeways in Riverside, Ontario, Fontana, etc. I see a lot of data speed complaints, but my existing phone works fine on sprint for Facebook, email, pandora, etc. Don't care about downloading stuff or streaming video, but I would like to use iphone 4s maps/nav in the car, stream Pandora, etc. Acceptable? any comments from users in this geographic area?
