OK thanks then I'll try to root my device, I have to say that if Sony would have supported more formats I were already satisfied! Yesterday I've read some pages of an EPUB and respect to PRS-350 the difference were enormous: "paper" near white instead of grey, totally styled text (bigger size, bold, italic). I've to try yet how the browser work.
A question I've some e-book in ODT format and I don't like to convert them (Calibre is great but, at least when I tried some conversions, I've obtained any more formatted file and sometimes without style anymore!) so what I could use to read them?
It seems that neither FBreader neither Coolreader support them, right? Strange they support DOC and not an Open Format?
I've seen this app "Open Document Reader":
It works on PRS-T1/T2?
