Yes, I was lucky...the software came bundled with other stuff I bought. I have no idea how the trial version works (or not), sorry.
There are some other similar apps, I believe. Someone suggested them in another thread (not sure where that thread is now).
As to the jailbreaking - again, no idea. I haven't upgraded to iOS 9 yet (because I have no doubt that something else I use will no longer function) but as to what happens with iTunes etc...personally, I don't care because I don't use it (worst designed software ever) and only use my iPod Touch for reading, so hopefully, I'll never have to open it again
