Get used to it. EPGL is great for hyping their news more than necessary. The price takes a tiny jump, and then slips back again. It will happen this time, as well. They're just trying to buy time, and hoping to actually have a product before another company (or companies) do.
Tomorrow they're probably going to give a few more sentences on At&T, and tell us how they're becoming major players and how this time its really the start of something big. They've been doing it for years now, and after tomorrow some on this board will be calling for a PPS of 5-45 dollars.
