Daily use of Neo1973

[Kevin Dean]

As a side, my wife has a Motorola W490 and before that we both had
RAZRs and none of the chargers (car or AC) work with the Neo for fast
charge.

I've heard an IRC rumor that someone has an applet that will force the
Neo to accept fast charge without the "handshake" on any USB charger
capable of pushing the needed power.
