Finally I've done it!
I don't known what's was wrong before
The first I've noticed is that is little difficult to see the icons, they are too small and there is a sort of lack of contrast, it is possible to make them better visible? Launch PRO is the solution? In the screenshot it seems really better...
What is the better reader between the ones installed?
Do you have tried a comic reader? What is the best?
It is possible to show the reading book cover on standby? It gives a really bookish touch to the reader (Sony PRS-T2 did this and I liked it much....)
