This webOS ROM leak just keeps getting better and better. The PreCentral guys have reportedly found in the code some interesting tidbit in the that distinctly references two different devices: "castle" (likely the codename for Pre) and "pixie," which we have previously heard as another name for the rumored AT&T-bound Eos. Is this a sign that Palm's oft-whispered Pre successor is revving up just around the corner? We can only hope.
