I used to read on my iphone so I had most of my ebooks as epubs. Then I got a kindle touch which I loved very much in the beginning. I also happened to have a lot of free time on hand a few months ago, so I converted all my books into mobi via calibre and later when my neatness fixation kicked in, I deleted the original epubs. Now I'm switching back to reading on iphone and want my epubs back again.

So my question is, how much does it lose to convert a file from epub to mobi and vice versa? Is it a lossless convertion or a lossy one? My books are mostly literary fiction without complicated diagrams or special characters and I don't mind the occasional screw-ups in format as long as I can understand the books. Should I just convert the mobi files back to epubs or would I be better advised to find and re-download those original epubs again?

Many thanks to you in advance!
