Ebook Generator

I am thinking about buying a new mobile…. In addition to using as a phone I need to read ebooks (mainly PDF including comics) as well as edit and/or view word, powerpoint and excel files. Which mobile do you think is the best. Or should I go for a seperate PDA rather than getting a PDA phone

recently i downloaded several ebooks and however i thought they are pdf but they weren’t.they were LIT.what are LIT files?how can i use the?
(i have win xp )

I have some PDF, some .lit and mobipocket books… I want to sell them
