I use Seesmic for iPhone when I need to use multiple accounts (my personal and MP account). Most of the time I use Twitterrific.

So of course, just like clockwork, Tweetie stops working today - and it's no longer findable at the App Store. I'd never heard of this twitter client problem before reading this thread today, so forgive me if I blame this thread for the whole thing - because I know this wouldn't have happened it I hadn't become aware of it.

Anyway, I guess I'm in the market, so let me go back and read other people's suggestions. Bah.

I use Echofon (the free version). It cloud-syncs with your iPhone, so when you leave your desktop and move to your iPhone, you don't have hours of tweets to re-read. It also supports location, url-shortening, pics, etc.

Hmmm, i may try that - even though i've just been informed that Tweetie now goes by the strange and confusing name "Twitter" - but should have triggered an update reminder on my phone just like all the other apps do - - - 17 times per week!

I just use the twitter app. I don't like the ads on Echophone.

Beware the Rainbow tweet.

What about the double rainbow tweet?

What about the Triple Dog Dare?!?

Is there any truth to the Twitter Virus rumor I've been hearing today? (I won't log on to Twitter because of it.) Purportedly, you can be "infected" simply by mousing over the virus link in some retweets. Is that kind of thing even possible?

It's been patched.
