My 2 Cents: Been having a lot of fun with the new AppleTV 2G especially since we have been able to jailbreak it with pwnagetool 4.1. I still am pretty impressed that it only took 1 day to get an app on it…too nice. I cant wait to see some more of the native iPad and iPhone apps. I tried the steps below myself and it worked like a charm (will need putty…Google it in order to access your AppleTV via SSH)
nitoTV on your (jailbroken) Apple TV2 (via Mac Rumors)
nitoTV is burning the midnight oil and has tweeted a new repository from which you can grab the first GUI-based AppleTV2 app (technically a Lowtide plugin), which currently has weather and RSS functionality.
To use it, do the following:
1) SSH into your Apple TV2, the default password is “alpine”
2) Type “passwd” and enter a new password (if you haven’t already)
3) Type: echo “deb http://apt.awkwardtv.org ./” > /etc/apt/sources.list.d/awkwardtv.list
4) Type: apt-get update
5) Type: apt-get install com.nito.nitoTV
6) Type: killall Lowtide
7) Enjoy
