I bought a Blackberry Curve this weekend, without a data plan. I figured since my college campus was almost completely wireless, I wouldn't need it. Well, I found there were some dead spots, like my room, where I have no WiFi coverage. However, when I was messing with my Curve (it's fantastic!), I found that I could use applications which would normally require a data plan without an active connection. I can bring up the web browser and browse to a limited amount of sites (I say limited, because I can go to any site that are in my bookmarks). I can also use the Gmail App, Google Maps, Blackberry Maps, and the Facebook App-all without a Wifi connection. Now, I figure this has to be using EDGE, which I previously thought to be subscription only. I checked my e-bill on T-Mobile.com, and it reports nothing, so I don't believe I'm being charged extra. Anyone want to help clue in a clueless Blackberry newbie?
