So, for school I'm on a trip to Massachusetts from the Baltimore. We're on a bus and taking I-95 all the way up. My plan has been to surf the web on my iPhone on the way up. However, I've been experiencing some data holes, or places for like 10-15 miles where I have full bars and a "3G" logo but no data coverage. Before I left, I checked the map for data coverage on AT&T and supposedly there's data all the way up the I-95 corridor. My question is this: are there data holes, or do you think there's something wrong with my phone?
