Crunchyroll now has an iPhone streaming application, so that you can watch all those cool shows on your nice little portable device. It's ben up since January 14th-- presumably as sort of a beta run, since press release-happy Crunchyroll didn't ship one out.
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.
