Hello /r/beermoney, i have a specific start up question

So, i've been a lurker here for a while because i thought it might be useful and i have only just realized that i have an old ipad 2 sitting in my room.

I know there is a get started here button on the side, but my question is specific and i could not find it there.

What is the most efficient/profitable thing i can do on this ipad I sit in my room almost all day so could be using it. It is also worth noting the Ipad 2 is on ios 7.somthing and is jailbroken.

Thanks for bearing with me, i am new to this.
