I would like to buy the Droid Eris, but I dont want to purchase the data plans that are included. My family is currently using the family share plan, and I would like to add a line to it. Is it possible to buy the phone and stick to the family plans instead? I still would like to use the features included such as email, web browsing, and the apps, so is it possible to do all these things using a Wi-fi connection instead? Please reply soon.
