Popular iPhone ebook app TextOnPhone is now available as an Android application in the Marketplace. So far, it’s the best ebook reader available for the T-Mobile G1. There are about 30,000 books that can be downloaded, mostly public domain and Creative Commons titles. You can also upload books to a personal bookshelf on the textonphone.com web site from a computer, and then download them to your phone. I successfully uploaded a short story, but I couldn’t get a full-length novel to upload for some reason.

The TextOnPhone Android application doesn’t support bookmarks, but it does a good job of remembering your place — even if you close and then re-open a book.

It would be nice if TextOnPhone could open text files stored on the phone’s SD card, or if I could at least figure out how to get large books uploaded, but it will do until a more full-featured application shows up.

UPDATE: Uploading books to TextOnPhone seems to be working fine now via the Facebook app. Go to the TextOnPhone web site to install the app to your Facebook account, and have fun uploading your books. The G1 application itself has also been updated — books are now downloaded to the G1′s storage card instead of to the device’s storage (only five books can be saved to storage at a time). And books can now be read online, without downloading first (like on the iPhone).

Finally, books can even be read on your desktop pc, via the Facebook app. The TexOnPhone developers are definitely on the ball, and this is easily the best (and most improved) G1 ebook application — not to mention my favorite G1 app of all. Thanks guys…I can finally stop carrying around my old Treo 650 just to read ebooks on!
