Hello...new guy here. I have never jailbroken before, and I'm new to Apple altogether. Just got my Ipad last month, and I love it, but I need Flash (or "Frash", I guess). A few JB questions that I didn't get answered by searching: If I use Limera1n, do we know if it will play nicely with the next Apple upgrade? I understand that Apple cannot patch a bootrom exploit (fancy new words for me), but will the exploit prevent Apple upgrades from working? Also, a REALLY basic one: Is a bootrom exploit reversible by restoring, just like the old exploits? Thanks.
