I would think 2.2 (w/ JIT) would solve the lag issues, but who knows. I have a hard time believing that the lag is at all related to the new OMAP 3630 cpu.
Darkseider, do you have any links that talk specifically about the Droid X having a signed bootloader? I know that Motorola chose to do that with the Milestone, but it seems like it was a conscious decision not to do it with the Droid. I have read speculation about this happening with future Motorola phones, but I never saw any real evidence stating that Moto planned to do that with the X.
Ask and you shall receive.

Second or third response after my initial post.
Motorola knows how to lock down a device when they want to... case in point, the Milestone.
let's hope the X is more hackable, but with wifi tethering a possibility out of the box, i highly doubt it
