For what it's worth....I spoke with Sprint this morning and they said that we would be able to preorder this Friday. They CSR also stated that I could use upgrades from other phone on my account....but suggested if I do use that method, I should perform the upgrade at either Bestbuy or Radioshack because those 2 stores process rebates instantly.
I'm considering this move heavily....Currently i have the Evo 3d.
If anyone would like to talk directly with a Sprint CSR, here's a good number. No phone tree....2 rings and your talking to a live perfectly speaking english CSR.
