Any way to get the old one back? Before the update. I am jailbroken.
Do you have a backup of the previous version?
Exactly. If you want to stick with the Twitter app, the version you replaced with the update should still be in your Trash/Recycle Bin on your computer. Just delete the one currently living in your iTunes library and restore the older version in its place (i.e. move the file from the trash and back into your iTunes library). Sync your device and you're good--BUT remember that you won't be able to update the app in the App Store, and also won't be able to use the Update All button on your device without having to do this process again afterwards.
