Hack a Nintendo DSi? (What exploits are avalible?)

I spam a lot here, lol
It's me again, this time trying to hack a Nintendo DSi. But I don't really know where to start.
I just ask a simple question: Is my Nintendo DSi hackable? Here is some stuff about the console:


Version:
Version 1.4.5E
European Console

DSiWare:
Flipnote Studio (I know you have a new exploit called 'ugopwn', but
DSi Browser
Dr. Kawashima's Brain Training - Words (& something else)
Dictionary 6 in 1 with Camera Function
Nintendo 3DS Transfer Tool

Flashcart & Gamecarts:
R4 SDHC (Works with 1.4.5E, runs in DS-Mode)
Art Academy (DSi-Echanted)


Please let me know if an exploit is found/possible to run!
