Just looking for opinions on Twitter Clients for the ipod touch. Right now I am using the free version of Twitterific and tried out echofon. I like Twitterific but I would like to have push on it. Which clients have push and what are some of the most popular? Just for some more info I use Tweetie on my Mac and UberTwitter on my BlackBerry. Thanks for the help, and feel free to suggest any apps you like as well as I just got my Touch and am doing some major downloading!
