Possible to use both Sprint buyback program and HTC Trade up?

view story

http://forums.androidcentral.com – I see that Sprint has a phone buyback program which will give me around $100 for my HTC EVO 4G LTE. HTC is also offering a "Trade Up" program giving people who buy an HTC One a minimum of $100 for certain smartphones. So here's what I'm thinking: 1) Use Sprint's phone buyback program to get $100 for my EVO 4G LTE 2) Use my old Palm Pre2 phone for the HTC Trade up (which they will give me $100) 3) Get the HTC One! Has anyone tried this? I think it's doable, but I'm not sure if the HTC offer is linked to any Sprint buyback program. I know I can probably sell my EVO LTE on eB (HowTos)
