So I have family plan with 4 lines with ATT. One Iphone, Blackberry curve 8310, blackjack II, and Nexus 1. Iphone has the iphone data. Blackjack II and N1 have data blocked. With the Curve 8310, I was using it without data for the past 2 years and gave the phone to my mom after I purchased the N1. Yesterday, she gets a text saying they added the $30 data plan on it. Now, when I logged in to my account and tried to get a non-smartphone for her, I got a message stating that I can't upgrade until July 28, 2011 (same for all lines). Is it possible for them to just renew all 4 lines for 2 years without our permission? Just a few days ago, I saw promotional prices for upgrades as I was thinking about getting a new phone and now all the phones show regular prices. Also, is it possible to block data on the blackberry?
