The iPhone version of iTweet.net now offers search and #hashtag support.

I've added Twitter search and #hashtag search to
iTweet.net's iPhone interface. I did it before I took off for Macworld last week, so I could see who was talking about what. Unfortunately, this didn't quite work out as apparently we Twitterbugs got a little excited with Macworld fever and
crashed Twitter right down. The API didn't become usable till about 24 hours later!

I started tracking "macworld" that morning and my IM sounded like I'd
won a jackpot!
I had to turn it off 'cause it was way too distracting.
Anyway, #hashtag support is in as well,
#hashtagged words are green. Click them to see an archive of words with that tag. For now I've decided to strip the preceding # off of the tagged word to make the system totally legible.
I made the search button in the menu
BRIGHT RED just to beat you over the head with it for now. ;)
Search is provided by the
Terraminds Twitter Search API.
