Don't "give up", we all know the phone exists and will be released this year. We've seen video of it "in the wild" and know it's out there, being tested. We know it's going to Sprint and that Sprint is set to release it's first 4G phones by the summer, what better phone to flagship the 4G launch than the Supersonic?
My guess is that we'll see the phone by July at the latest. Which would work perfect for me to jump ship from AT&T and my iPhone 3G since my contract ends in July. I'd love to see the phone earlier than that, but who knows. Hopefully they announce more details later this month.
I can't say much, but can say that the specs posted in this thread are MOSTLY correct.
