I see that Pocket has posted an update on their site about availability on other kobo devices:
(Update: As of Monday, September 16th, Pocket will be available on the Aura, and updates to existing devices including the Glo and Aura HD will be coming over the coming weeks and months. To check support for additional Kobo eReaders, please contact Kobo Support.)
