This was me as well. Which expansion did you do that for? For me, it was wotlk and it was really fun at the time but looking back, nothing particularly memorable happened. Except that I went home and had to install the game so I didn’t get to play till the next day anyways.

I personally wouldnt bother with the jail breaking if you can. Ive had good results just putting mine on airplane mode and using Calibre to manage my library.
