Another update to the A World of iPhone Links page. All links are iPhone- and iPod Touch-friendly or generally designed to be accessed on a mobile phone. Enjoy.

American Airlines - Check on your reservation, check-in status, or flight status. Book or change flights, find specials on fares, view your Miles, request upgrades. Basically, everything you’d need for traveling on AA in a well-done iPhone-friendly site.

The Beatles (fan site) - Anything and everything about the Beatles. They’re not on iTunes yet, but they’re on the iPhone.

CBS News - All the news that’s fit to print…err…view on your 480X320 dpi screen with high-grade optical glass.

Food Information Database - Food information site featuring calorie, fat, carbs, etc. Features all the major fast food chains and restaurants. Barebones site, but useful.

Fox News - Fair. Balanced. Use the iPhone’s accelerometer to balance the news.

iZodiac - Horoscopes for the iPhone inclined. Simple, sweet, good-looking site. Discover your tomorrow today. Will the iPhone be your Cassandra?

Tittr - Fun little photo microblogging site. It’s simple to use: snap a picture with your iPhone and email it to Tittr.com at geemail (as in Google), and it shows up on the site, tagged by whatever you enter in the subject line. Fun to see where people are using their iPhone. Important caveat: the name you use with your email shows up next to your photo, but your email address is hidden.

Wikipedia - The best iPhone Wikipedia site yet (there have been some bad ones). Features full Wikipedia posts. Definite bookmark.
