Hi everyone!

This is the first time that I'm replying on the list but I have been 
following the list every since it started. A few days ago I put my order 
in the group tour. Can't wait to get rid of that buggy gprs connection 
in my Freerunner :).

Can't we just add an item in the u-boot menu for fast charging? 
Sometimes you might want to charge the phone without it booting for 
variety of reasons so it could be useful in other situations.
