How to tell if an iPhone has been jailbroken ???

[WowIndescribable]

Hi guys, I was not able to find the answer to this question so I'm posting it here.

I have a *factory (Apple) unlocked* 3GS (3.1.2) that I would like to upgrade to iOS 4.x However, I am concerned that if it has been previously jailbroken that doing so in the normal iTunes fashion might result in a brick.

How can I tell if my phone has been previously jailbroken? There are no unofficial apps on it to indicate that this was done - but they could have been deleted.

I don't actually care if it is jailbroken (I don't use any unofficial apps), I only care that I can continue to upgrade it in the normal fashion without ruining it.

All comments are welcome.

If its been restored to factory then: 1) There is no way of knowing unless you take it to a data recovery lab; and 2) there is no danger of it bricking.

Once its returned to factory it in essence is exactly like a factory iPhone. Its software...

Even being jailbroken, won't effect how it works with iTunes.
