Here's a service for those Twitterers (Tweeters? Twittererers?) out there. Free Tweets by phone:
Quicktate (http://quicktate.com) announced the launch of TweetCall (http://tweetcall.com), a new service that allows users to dial an easy-to-remember toll-free number, (877) Tweet-Call, to “speak their tweets,” which are then transcribed and uploaded to Twitter.
TweetCall is the perfect solution for those lacking the skill, patience or time to send SMS messages conventionally, or those wishing to post tweets while driving. In fact, TweetCalling is faster and easier than texting.
More here. I tried it out with a simple "test message," and the update hit in just a few minutes, and was entirely accurate.
