Last summer I bought a pair of Palm Pres at launch...one for me and one for my girlfriend. It's been a mixed bag as I like a lot about the Pre but I also am ready for an upgrade. Somewhere along the line I ended up with a $150-off eligibility on her line. Not sure where that came from but it's there on my account. Anyway, I am hoping to pick up a Supersonic when it comes out sometime in the next few months if rumors are accurate. If it is not out until June this is a moot point as both lines will be eligible for a yearly update but if it comes out in a week or a month I would love to use that $150 off. My question is whether or not I can just have them switch the discount to the other phone. We are on a shared plan with two identical phones. I just don't need to upgrade hers just yet and was hoping there was an easier way than upgrading hers then swapping ESNs. She is not keen on any scheme that risks screwing up her number or her phone (even though the bill is in my name). Any Sprint folks care to chime in on how likely it is to get CS to just move the discount to the other line?
