Almost 2 months ago, my wife and I got a Droid and an Eris. She HATES her Eris (slowness, low resolution, you know the typical complaints...) Anyway, here's what I'd LIKE to do. 1. Switch her number off the Eris to a dumbphone we have laying around. 2. Buy an Incredible at Best Buy 3. Sell Eris on eBay 4. Cancel dumbphone line, using money made from Eris to pay ETF... OR - could I switch her number to the dumbphone, and then just not cancel it and pay the additional $10/month for the extra line? Am I missing something, or is it this easy?
