I was wrong in my previous post.
Here's the sequence:
- I have an Adobe Digital Additions account which I had already set up on my Sony PRS-600 successfully for buying DRM'd books and borrowing them from the library.
- Today I "authorized" my Pocket Pro for ADE for the first time, while LBook firmware was on-board. And when I tried to read the books I had loaded using ADE, none would open.
- So I next put the latest Astak firmware (March 2010) back on, and all the ADE DRM protected books became available.
- In the interest of being thorough, I cycled through Jinke, Papyre, BeBook, and finally, LBook firmware, and I found that the DRM books opened within each and every one of them.
To be clear - this seems to work because the device has been authorized be Adobe Digital Editions, and the authorization doesn't appear to be tied to the firmware.
It was interesting comparing the different firmware. They are all pretty similar, except that BeBook and Papyre both use the previous version of CoolReader (looked similar to the version on the December 2009 Astak firmware). They all had TTS for English, or "Ingles" in the case of the Papyre
It will be very interesting to see how the newest Astak firmware compares.
Sorry for the mis-information!
