Okay everyone -- grain of salt goggles on? According to PhoneNews, not only is a GSM version of the Palm Eos (AKA Mini Pre, AKA Pixie, AKA Castle) coming to AT&T sometime in the near future, but Sprint will be getting its version of the Centro-like device come Q3 2009. The site claims that "sources within Sprint" have "confirmed" the launch window for a phone with specs similar to those on the device we hit yesterday, and that said device is actually in testing right now. Of course, just as we mentioned with the Eos news, this isn't actually confirmed by anyone at Palm (or even close) right now... and you know how much the internet loves a rumor. Still, this would make a lot of sense as Sprint and Palm are all but joined at the hip, and it helps jibe some of the differing reports we / the blogosphere has heard about carriers. Obviously there's much, much more to this story -- you'll know about it when we do.
