My wife has a crappy LG phone that she got last year so she's not eligible for an upgrade yet. I have an upgrade available for my phone, so I'd like to use that upgrade to get her a Backflip. Amazon has it for $49 (upgrade price), but when I try to order through there it automatically adds a $30 data plan. She already has a data plan on her phone so I don't need the second one. So... can I buy the phone from Amazon as an upgrade for my phone, put her SIM into the Backflip and then cancel the 2nd data plan? I poked around on the Amazon wireless site and saw some text about being responsible for an ETF if I cancel the entire plan, but couldn't find anything about canceling just the data plan. Anybody know?
