There's a flex tweak for the ipad version of sky sports app where u can watch all the sports channels. Really frustrating that we can't use Sky Go. Pay enough for the service!!
Well it's not them that requires it. It's the content providers, mainly sports and movie providers. They're just protecting their content. It's no different than copy protection used for VHS or DVD. They want to protect their assets and a jailbreak lessens their ability to control how the video is used (ie you can get jailbreak tweaks that override the output controls then rebroadcast it, or tweaks that spoof the location that allows you to view the content when you're contractually not allowed).
Like it or not, you're not entitled to the content on a jailbroken device just because you pay for it. You pay for it in agreement with their terms and conditions.
