yes. I have one on my Droid. I think it's PlurkQ but you should be able to find one in the apps or market for the phone that you have.

It depends on your phone. You can access it from the internet browser on your phone with plurk.com/m

I use the Plurq app for Android and it works really well.

I'm using UniPlurk on my iPhone. Used iPlurk for a while. Uni is better.

found a mobile version for iPod touch, might work if you have an iPhone...

I use UniPlurk on my iPhone, too!
