Back in the day when iOS 2.0 was popular and it was so much easy for us jailbreakers to get Cydia on it. All you need was your iOS device that you want to jailbreak and Safari, which is the default browser on our device. No computer was needed to jailbreak iOS 2.0. This was thank to a utility called JailbreakMe. If you don’t know, the unique part of JailbreakMe was that it’s a browser-based jailbreak tool. This means you don’t need a computer or any type of machines except your own iOS device.
Last month, a company called Zerodium was trying to bring the same concept and apply it to the new iOS 9. The put out a $1 Million award for any hacker or team could achieve this. The event ended today and luckily a team of hackers were able to make a browser-based jailbreak for iOS 9.1 and 9.2 betas.
