Gregory's Server@samhenrigold @grishka the source for the jailbreak version of Twitterific is up on GitHub: https://github.com/chockenberry/mobile-twitterrific/
I never really did jailbreak tweak/app development, but looking at the source for Twitterific, it looks like at least UITableView wasn’t a thing on iPhoneOS 1.x. Other stuff probably also got refined for the 2.x SDK from the 1.x OS.
@grantjbutler @grishka change in plans, the new weekend goal is just downgrading the phone to 1.x. and then development will be a stretch goal lmao
