As many others, I will be purchasing the EVO on a line that is eligible for a full upgrade within my family plan and then switching it to my personal line. My question is... what is the easiest way to switch phones from line to line? I don't want to waste anytime on the 4th! I want that bad boy on my line ASAP. I've been told you can do it at a Sprint store, over the phone, or online myself. I just don't fully understand the process. Do you have to de-activate a phone before switching? What about the de-activated phone that the upgradeable line was using before we bought the EVO? Any help would be appreciated... 2 more weeks to go fellas!
