I'm not exactly sold. The last "Required Update" I got from Cydia resulted in my iPad becoming bricked. It's made worse because they way Cydia is developed, you normally are already into the update process when it insists you update ALL the updates, and you can't check them one by one. It eventually recovers, but the last time the iPad was useless for more than a week. I was about to do a fresh install, meaning I would no longer be able to JailBreak it (it's an iPad 2). As a result, I've sworn to NEVER accept a Cydia update again. I'll just wait until the next jailbreak when I'll have to reinstall the iOS all over again anyway.
This is an example why you should NEVER rely on a single vendor for ANY product, even a jailbreak! It results in lazy, cludgy programming and BAD products!
