    I have a 3GS 3.1.2 jailbroken. I never got into the scene, and as such never really did anything after I jailbroke it. Anyway, I'm a tester for a dev. I want to update to the 4.0 beta. I have a few questions about this process.

    First, can I just download and install 4.0 and expect it to patch up and remove my current jailbreak? I don't mind losing the jailbreak, since I never utilized it. Does this cause problems or "flag" my phone as tampered, or just a clean install and fix my jailbreak?

    Alternately, should I do a full restore on my iPhone before the upgrade to ensure there are no problems? That seems fairly time consuming, and I'd like to avoid it if possible. Also, since I've never done that before, does iTunes retain my contact info? If I did the "delete all content" restore, I am hoping iTunes keeps that info for an easy restore.

    Sorry for so many questions. Hopefully, someone can understand that mess of text and help out.

    No, no, and no. If the dev wants you to update to the 4.0 beta, have him give you explicit instructions - he will have to add you to his account anyway to get you the beta. If you don't do it right, you risk serious damage to your iPhone. (Read @iMuggle's great posts on the subject.)

    I would also add that unless you have another iPhone that is your primary device, I wouldn't do it. Too incomplete, risky, and unstable.

    None of these 'warnings' stopped me from using 3.0 last year, honestly. *lol*

    It's cool though, to each his own. Trust me, if he really wants to do it, he'll find a way.

    Last year with 3.0 the file system had not changed. This year with 4.0 it has.

    I thought the iPhone didn't have a file system? There's no way to save documents, browse to attach files made in office related programs and the like. Isn't that one of the complaints of the iPhone OS in general? That it doesn't have a file system?

    Yes there is, just not with a stock iPhone. On a jailbroken device, you can do everything you just mentioned once you figure out root access....

    Please note the difference between a file system and a file manager...
