I am not sure if you guys know this or not but rather than waiting to sell our phones on ebay or craigslist, we can send it back to sprint and receive a sprint credit. I just checked on my palm pre and even though it isn't much (it's $63) at least I won't have to worry about selling it on ebay and paying for shipping.
