We last covered the iOS RSS reader Byline back in May of last year, when it had just hit version 3. Now the app's been updated to version 4, and it's still an excellent RSS reader for both the iPhone and the iPad. Version 4 brought universal capability to the free version of the app (it has ads, though you can get rid of them for just a few bucks). The new version also adds an easy way to "Mark All as Read" (just slide the "Edit" button), and the 4.0 release (as well as the minor releases after it) fix all kinds of bugs and add in some performance improvements.
Byline still hooks up directly with your G
