Apparently the new iPhone will stay connected to wifi even while the screen is locked. This is nice because with my current iPhone, I use about 3-4 megs of data a day even if I never leave my house (which has wifi). It would be nice if the Captivate didn't do that since I have the 200-meg plan with AT&T and I'd like to use my data for web surfing, not checking for email in the background. Would anyone mind checking this for me? Thanks!
