Till now threre’s no jailbreak available for iPad 2, but you have to know that Comex -the hacker behin JailbreakMe- is working now on iPad 2 jailbreak via userland exploit.
Bootrom exploit is difficult to discover and develop than userland exploit, as Bootrom exploit is hardware-based exploit so that it can be fixed only with hardware upgrade which means that it will also work with upcoming iPhone 5, so we can conclude that bootrom exploit has long lifetime. Userland exploit is a software-based exploit so it’s not time consuming compared with bootrom exploit but, its weakness that it can be easly patched on firmware upgrade.
There’s no ETA for iPad 2 jailbreak so far, but iPad 2 users should be optimistic as we will have more than solution for jailbreaking the lovely iPad 2.
