Data Roaming? What does this do?
What exactly is "data roaming"? I get a very weak signal from AT&T at work, but they have the Verizon repeater there so everyone with a Verizon phone gets great coverage. Doesn't data roaming mean it will pick up the signal from other carriers and provide data coverage?
Thanks for anyone who knows how this works!
