> I never did much beyond installing Cydia.

Watusi was great, it let you disable the blue checkmark on Whatsapp. (Since been added as a setting)

I also used a tweak that let me auto-block certain phone prefixes that spammers used. Quite useful.

Was also useful that it allowed you to install multiple copies of an app (such as whatsapp), though no longer a need for that either.
