There is quite a bit of worthwhile homebrew at this point. Just explore a bit it's fun.
Though most homebrew that will have longevity will be emulators. If you haven't played SCUMM games before ScummVM on 3DS is not perfect but works well enough, and let's you play some of the most fun Point and Click games out there. Other emulators are pretty self explanatory.
HANS alows you to use romhacks, there are a few good ones out there.
You can check what you can do on the wiki under homebrew app/games and there is also a list on 3dbrew.org.
I would definitly not return the game. There will most likely be a new ARM11 or ARM9 exploit released sometime, no reason not to just hold on until then. Or you could install a secundairy exploit and return the game of course if you have any other exploitable game (I hacked my 3DS's when 9.2 was latest FW so haven't kept up with other *hax exploit's but you can find them at smealum.github.io/3ds)
