I came across a genius post today indicating that you can use EQO Mobile for Twitter updates: Posting to Twitter from your Phone with EQO Mobile. Thank you to Rob Rogers of Digital Streets for enlightening us! While I know there are many ways of sending twitter updates from a phone, this is just one more thing you can do with EQO Mobile, which already provides MVoIP, Messaging, and IM. I already had Twitter on my Google Talk contact list and am now using EQO Mobile to send Twitter updates using our IM Chat. Give it a shot, it's cool.
