I'm confused about jailbreaking...

[skizo]

I used this to "upgrade" to 2.0.2 today, as well as unlock my phone.

Is my iPhone jailbroken as well?

yes.

K...thx.

I was a bit confused as everything seems to be going tits up. Apps are crashing left and right.

Tried downloading Shazam. Crashes before opening.
Tried downloading Modomi. Crashes before opening.
Tried running a 3rd party file transfer app called Iphone PC Suite. Crashes before opening.

I'm having a slew of other issues too, but if you're saying it's jailbroken, that's one thing I can cross off the list.
