So, I have Veteris, an app installer, on the iPad 1 that’s jailbroken. So far, I got Alien Blue to partially work and I can’t make comments but can read them and posts. I also got Tumblr to work. Is there anything else I can use on it that’ll work that you’ve tried? Maybe old social medias? Maybe I can get something from the Fediverse to work on there? I mean, it’s ~16 years old…
You should install an eBook reader like MegaReader; if you run your own Calibre server, it does a good job of reading books.
Realistically, there’s not going to be much you can do with an iPad 1.
An iPad 2, on the other hand, is still a very functional jailbroken device. SNES and older emulators work great, it can play streaming videos, works with various ePub and PDF readers, and handle email and site-specific web browsing (including Lemmy).
