Phantom Fish and CoolLittleThings have teamed up to give away 42 copies of both Byline and BlogPress. If you buy one app, you win a chance to get the other for free.

Three winners will be chosen every day beginning the 18th, and ending on the 31st. The promotion is available to anyone who purchases either Byline or BlogPress between today and the end of the year.

Depending on which app you buy, you must email a copy of your iTunes receipt to the app's publisher to be entered into the contest. Full details and instructions are available on both the Phantom Fish and CoolLittleThings websites.

Byline is a Google Reader client and offline browser for the iPhone, which I reviewed in October. It's available for $4.99 in the App Store.

BlogPress is an easy-to-use WYSIWYG blog editor that supports all the maintream blogging platforms, including Blogger, WordPress and Movable Type. It's also available for $4.99 in the App Store.

Phantom Fish yesterday updated Byline to version 2.0, adding functionality to browse by tag, and a spiffy new wood-grain interface.

I briefly reviewed Byline 1.0 in July, but wanted to re-visit the application after the update. Byline 2.0 is a Google Reader client and offline browser for the iPhone and iPod touch. After having used beta versions for the last few weeks, I can say with certainty that this update takes Byline head and shoulders above the first version.

Byline 2.0 is faster than both version 1.0 and Google Reader's MobileSafari-optimized interface. Articles are now grouped in folders according to tags you've already set up in Google Reader. You can mark whole folders of items as read, and save items to your phone by starring them. The app doesn't show a splash screen at startup, but instead a "blank" version of the interface, which gives the illusion that the app is hanging for a short period of time. As soon as the list of folders appears, however, loading items was zippy on my iPod touch (connected via WiFi, of course).
