While perusing the /r/jailbreak boards this weekend, I was reminded about a website that once existed for the specific purpose of passing APT repositories through a URL using the ‘?source=’ parameter, which would then present the end user with buttons to add that particular repository to all available package manager apps that the user might have installed on their jailbroken device.
New jbredir web utility makes it easy to add repos to several package managers on jailbroken devices
