Durarara!! on iPhone
If you have a WiFi connection on your iPhone or iPod touch you can give it a shot. I'm betting that our own AHR may try it out, since she's been enjoying our Crunchyroll account-- but beware! You can't get early access to simulcasts on your iWhatever, even if you're a paying user, and you have to manually turn on subtitling-- but don't worry, paid users do still bypass ads.
It'll be interesting to see how this develops; as someone who will most likely be owning an Android phone in the near future I hope they're working on an Android app as well! Those of you with iDevices, you can download the app right here.
Flash 10.1 on Android doesn't work on video sites quite yet. The next Android update won't be until March so there's still time to work out those bugs.
@HSaabedra: It varies; YouTube works fine on my friend's Droid, but our videos on Vice, not so much. Which is why we have an Anime Vice YouTube channel! </pimping>
