Need to get the wife a new phone. Original Droid finally crapped out. We are on the 1400 minute family plan w/ unlimited everything (text,data) You know, that special that can out on email back in Dec-Jan timeframe. If I renew her contract and upgrade her phone through Walmart (Droid X2 $99.99) will that change my plan and make us loose here unlimited plan? I have no experience with purchasing cell phones through Walmart, only Verizon. Any experienced peeps replies would be great.
