Deleted native (built-in) apps on my iphone 4s

Or choose to play around with the file system with the intention to learn when you can still restore to a jailbreakable firmware!

Bam, best advise.
I see way too many people messing up their JB by playing with things they're not supposed to.
And now that you cant restore to Jailbreakable firmware you'd be staying stock for a while.

I have never been a jail breaker myself. I appreciate what the jail breakers develop and put out there, but personally I do not leave Apple's "sandbox" as I do not find the need to.
