Good news. Several days ago I've received a present from PocketBook - PB602 Pro.

Many thanks for it!
Today I made build of FBReader180 for PB 60x/90x (at least I think it should work on 90x).
It's just a test version because there is no official SDK.
I've used custom toolchain from
sergeyvl. Thanks to him.
So some features may not work or may work improperly.
Please, be ready for this.
This version has the same features as 0.9.2. It's just adapted for new firmware.
It's here:
0.10.0.
