I did a lot of research before my Le Pan TC 970 arrived, and I was all prepared to have to install the latest firmware but when I checked, I got an even NEWER version of what I thought I needed. Is this normal? I thought I would have to upgrade to 4626, but 4749 seems like it is newer? Is that right? Overall, I am in love with it already, unboxed it, charged it for 7 1/2 hours, and then played for over 2 hours Mila C.
