Hi, I'm a new HTC Droid Eris user and so far I love it. Unlike most of you though, I am using it on Page Plus Cellular. I have a plan for $30/mo, 1200 min, 1200 txts, and 50 mb data. The data of course is the drawback, but I don't plan on using too much data, and when I need to, I'm usually able to connect to wifi. Here's some questions that I had that hopefully some of you can help me with. 1. To receive or send MMS messages, does the Mobile network (3G) have to be enabled? 2. Is there any way to use the GPS without data? I suppose we would need some map download such as tomtom for it to work. Any ideas? 3. Does the trackball have multiple colors or just white? 4. Would the program Locale work with data disabled? 5. I'd like to setup Mail and Facebook and Twitter, but I don't want it to automatically update so I won't use up all my data when I enable 3G occasionally. Is that possible? Since I have 50mb a month of data, I would like to be able to just switch on the Mobile Network when I'm away from wifi and need to access the internet. I want to make sure that when I switch it on, it doesn't start updating everything. This is why I haven't setup FB or email yet. Also, does anyone know approx how much data some of these apps use? For example, if I want to Shazam a song, would it use a lot of data? Why about scan a barcode? And what websites are safest to use for news, etc. that use very little data? Thank You!
