FEMA
m.fema.gov/ (xhtml-mp)
The US government's Federal Emergency Management Agency (FEMA)'s innovative mobile site now allows disaster victims apply for FEMA assistance using their mobile phone.
FEMA's mobile site also provides information on emergency services in regions affected by a disaster and has general information on what you should do in the event of a hurricane, flood, tornado, earthquake, terrorist attack, thunderstorm, tsunami, wildfire or severe winter storm.

FactCheck.org
factcheck.org/mobile/ (xhtml-mp)

FactCheck.org is a non-partisan, non-profit project from the Annenberg Public Policy Center at the University of Pennsylvania. It researches and debunks false claims made by U.S. politicians and political action groups in campaign materials, speeches and in promoting legislation.
FactCheck has played a significant role in recent U.S.elections. In the 2008 presential campaign Factcheck.org flagged multiple falsehoods by both candidates, including Obama's statement that McCain's Social Security proposal would cut retiree benefits by 50% and McCain's claim that Obama lied about his association with anti-war activist Bill Ayers.
FactCheck is available in a mobile formatted version at factcheck.org/mobile/. I like that virtually all the desktop site's content is available in the mobile edition. However, the size of the pages (the homepage is 151 KB) means the site will not load on most non-smartphones. In spite of the increasing popularity of iPhones, BlackBerries and other devices with full web browsers, only 37.3% of U.S. mobile web page requests come from smartphones. Devices like the venerable Motorola RAZR V3 or MetroPCS' entry-level Nokia 1006 account for significant amounts of traffic and can not handle pages much over 20 KB. Given that FactCheck.org's content is mainly text it shouldn't have been very hard for the site's designers to follow the example of news sites like CNN, the BBC and even small town newspapers like the Elmira NY Star-Gazette and built a mobile site that could accommodate all browsers.

FBI Most Wanted
FbiMostWanted.mobi (xhtml-mp)
I got an email from Mark at Idea Earth suggesting I take a look at the mobile sites they have developed. Idea Earth's got a boatload of sites, but one jumped out at me as especially interesting and unusual was FbiMostWanted.mobi. It's just what the name suggests, a mobile version of the famous Federal Bureau of Investigation's 10 Most Wanted Fugitives List. The list has been around for almost 60 years and every American has no doubt seen the hard copy version of prominently displayed in Post Offices around the country. These days is online as well but the FBI hasn't had the foresight to create a mobile friendly version creating an opportunity which Idea Earth has taken the initiative to fill.
The FBI has supplemented the original 10 Most Wanted list with additional lists of the Most Wanted Terrorists, Most Wanted Sexual Predators, Most Wanted Murders, Most Wanted Robbers and Most Wanted Drug Conspirators and FbiMostWanted.mobi has all the lists too. The site also has links to the FBI's online form for reporting a fugitive and to a list of FBI offices. These links are not mobile friendly. It would be nice if Idea Earth linked to non-mobile sites through a transcoder like Mowser, Skweezer or Google's GWT There's also a click to call link to 911, just be careful you don't accidenly click it! Just a remainder, but if you ever do accidently call 911, stay on the line until the emergency operator answers and explain that you dialed 911 accidentally, otherwise you could wind up surrounded by emergency vehicles and possibly a fine for a false report.
FBIMostWanted.mobi was created with the free mobile site builder MobileSiteGalore which goes to show you that you don't need a big budget or impressive technical skills to create a compelling and useful mobile site.
Article99
mobi.article99.com/ (xhtml-mp)
The mobile edition of Article99.com Authors Club, a site where people who want to promote their business, website or reputation as a subject matter expert submit articles on any topic, a practice called Article Marketing. There are actually dozens of Article Marketing sites on the web but this is the first one I've seen that has a mobile edition. Article submission is free on Article99
As you might expect on a site dedicated to self promotion the quality of these articles tends to be pretty low, but some of the articles are reasonably well written and useful. Article99 has some fairly specific content and style gudelines and appears to moderate submissions to weed out the trash. There are over 20 thousand articles grouped into a couple of dozen main categories and over 450 sub-categories. You can find anything from dog training tutorials to web design tips on Article99. Unfortunately the Google powered site search doesn't seem to work making the site more suited to browsing than searching for anything specific. Considering the quanity of content, Article99 is reasonably usable on a mobile thanks to the use of accesskeys and the hierarchical organization.

Wikizap
wikizap.mobi/ (xhtml-mp)

The Taptu folks, who also own Wapedia, the best mobile version of Wikipedia, have apparently mobilized a bunch of other wikis and launched Wikizap, a wiki directory. It features mobile versions of such weird and wacky wikis as the Muppet Wiki, Wookieepedia, the Harry Potter Wiki and NFL, hockey and baseball wiki. And that's just of few of the mobile wikis on Wikizap. There are over 30 wikis in all on the site in English, German, French, Spanish, Italian and Japanese. Source: Oh! Mobile Directory

Wapedia
wapedia.mobi/en/ (xhtml-mp/wml)
Wapedia currently has the best mobile version of Wikipedia. It's fast, always up and does an outstanding job of adapting Wikipedia content to everything from five year old wml-only handsets to an N95 or Opera Mini. It works just like Wikipedia on a PC, to deliver the entire Wikipedia online encyclopedia including all images, charts and tables in your mobile browser. Wapedia splits pages and resizes images so that everything fits into the physical screen dimensions and the memory limits of just about any phone
Wapedia has a very fine-grained algorithm for splitting pages and resizing images. It sets maximum image width to anywhere from 91px wide for the Nokia 6230 to 310 px wide for the iPhone or G1. The same is true of pagination. Wapedia dynamically adjusts page size to fit handset memory. The N95 gets Wikipedia's huge Tokyo article as 9 pages while the old wml-only Motorola i85 gets 60 much smaller pages.
Wapedia has advertising, although it's pretty minimalistic, just a single text link at the top of each page. I hardly notice the ads, but if the thought of advertising on Wikipedia content bothers you, try Wikipedia Mobile.

Wikipedia Mobile
mobile.wikipedia.org (xhtml-mp/wml)
Wikipedia's official mobile site. How does it compare with Wapedia, my favorite Wikipedia mobile front end?
Both have a simple homepage dominated by a search box, not unlike what you see when you visit Wikipedia on a PC. Wikipedia Mobile gets points though for including the classic Wikipedia "puzzle globe" Iogo on the front page.
For a real test, I tried looking up "Tokyo" on both sites. The Wikipedia Tokyo page is big (814 KB) with many images and some double byte Japanese characters. It's a tough test for mobile front ends.
Both sites were up to the task of displaying the Wikipedia Tokyo page on mobile devices. Pages were split and images resized so that everything fit both with into physical screen dimensions and the memory limits of a variety of handsets. The double byte characters were passed though unaltered, they look like gobbledygook on most western handsets but will display correctly on phones with Japanese language support.
Overall I preferred Wapedia's presentation Some of the original page's content was missing in Wikipedia Mobile. Particularly noticeable was that the first few words of the article were missing so that the piece started with a comma! (2nd image) A table near the top of the page listing Tokyo's population, area, symbol, flower and other basic facts also did not appear in the Wikipedia Mobile version of the page.
Another thing I liked about Wapedia is that it has a more fine-grained algorithm for spliting pages and resizing images. Wikipedia resizes all images to a maximum of 128 px regardless of the phone's actual screen size, Wapedia alters maximum image width anywhere from 91px wide for the Nokia 6230 to 310 px wide for the iPhone or G1 which is certainly desirable unless you like squinting at tiny pictures. The same is true of pagination, Wikipedia Mobile uses two fixed pagination sizes, the Tokyo page is split into either 30 pages for WML-only phones or 18 pages for modern devices. Wapedia dynamically adjusts page size to fit handset memory. The N95 sees the Tokyo article in 9 pages while an old wml-only Motorola i85 gets 60 much smaller pages. Not only is Wapedia more likely to work on low memory phones but it's a lot faster and less annoying to press "Next..." nine times than 18 on a more capable phone.
One advantage of Wikipedia Mobile is that it's ad free, Wapedia has advertising, although it's pretty minimalistic, just a single text link at the top of each page. I hardly notice the ads, but if the thought of advertising on Wikipedia content bothers you, try Wikipedia Mobile.
Personally I plan on continuing to use Wapedia. But it's good to have alternative ways to get at Wikipedia's great content from handheld devices.
