I just ordered a pandora battery at http://www.acer-laptop-battery.com/pandora-battery-c-101.html, I do not get custom firmware. I have a 2gb memory stick that i was planning on using to make the magic memory stick. But, will I still be able to use that same memory stick for storing files and such after I make it a magic memory stick and get the custom firmware on? i really your best advice.
