At Last! New free tweak released on Cydia called "No Not Charging" which disables the "not charging" text which is displayed on your iPad whenever you are plugged into an underpowered charger or USB port. Coolness!
I'm not sure I would want this. I think I would want to know if it's charging or not no matter where I plug it in.
