READER for LG 800g: Try Libra. It is the nicest I've found for this phone after a lot of searching. You can use bookmarks, which is nice. I doesn't have the "share sections you like by SMS" function, you can't change fonts or screen brightness once inside the program, but all in all, a great way to pass the time waiting at a Dr. apmt. or going to sleep at night. A nice size phone for reading actually. I am not yet sure how to download books into the phone, several came with the reader I'm enjoying. I'll have to get to that next!
APPS: My favorite so far is called "shopping". I'm making myself put my list in my phone so that I'm less likely to use it. You just tap the touch screen on the item and it disappears to "bought", so make sure to lock the phone when you have it in a pocket.
Also, if you know you are dialing up the net just to check facebook, I like the facebook app. It's faster than bolt, though I could do more in Bolt on facebook, the app is a fast way to check on things.
No one knows the app you're discussing here (Libra) unless you give us a source for downloading the program. Like the other user I tried to find it through Google searches and only came up with a lot of dead ends. No sense telling us about it unless there is a place to go to find it and check it out...
