I called Advanced Tech Support and the rep I spoke to looked in his "knowledge database"? I think that is what he said. He found the issue with the 700wx right away.
What I found very interesting and a credit to those on this site that have contacted Sprint about this issue is that in his database there is a direct link to the PPCGeeks post for more information which has the details that Malatesta posted as an official explanation.
I thought this was really cool that Sprint is officially linking to this site for more detailed information.
Just thought I'd share this info. with everyone.
