We couldn't believe it either, but as it turns out, from the launcher screen of your Pre, simply type in the phrase "upupdowndownleftrightleftrightbastart" -- which if you parse with spacing might be more easily recognizable as the infamous Contra
/ Konami code (look it up) -- and up comes a hidden app called "Developer Mode Enabler." Looks like it was discovered via the leaked ROM
from earlier this evening. It's apparently used to connect a Pre to a machine running Palm's Mojo SDK for webOS, and we have confirmed its legitimacy. In fact, if you want proof and you don't have a Pre of your own, head on after the break for a video we put together, just for you.
