I would love an app which makes your BB ring/vibrate when a tweet/reply/direct message is posted (it's already possible for direct messages if you set up your blackberry email for receiving notifications)
I like TinyTwitter better. TwitterBerry doesn't wrap the message text, so I have to click the trackball a million times to read tweets. TinyTwitter wraps the text and has a lot of customizations available. I don't really see any reason not to use it.
You must have a data plan (TCP access) in order to use Tiny Twitter so I couldn't try it as I only have BIS... But anyway, I love TwitterBerry.
I don't know any other app, but you can also use the mobile website or IM to post tweets.
i have BIS and i use tiny twitter but i have data plan as well so that answer my own question
anyways, there are so many twitter apps you would be suprised....
i prefer twitterberry and tiny twitter....i have both on my curve and love it...twitterberry let's me post to my twitter account and tiny twitter allows me to respond/reply to my friend's timeline...
