    If I restore my iPhone to "factory settings", is there any way to tell that it has been jailbroken/unlocked (snowbreeze)?

    Is the snowbreeze-unlock permanent, and will the store be able to tell, if I (at some point) need to hand it in for repair or whatever?

    I pretty sure that it does, but I do know a restore erases all traces of a jailbreak

    just a factory reset clears all the user data (such as apps and media) not the data stored on the /var area of the device (where the jailbreak data lyes), but a full restored will remove everything and reinstall the main os

    The only thing that TRULY wipes all traces of a jailbreak is a DFU restore that doesn't restore from a backup. Everything else leaves very minute traces that could be detected if they looked in the right places. However, your normal everyday Apple employee wouldn't look that hard, they would just give you a new one, provided it's indicator and under warranty.

    What is the difference between factory reset, and a restore? For example; if I use iTunes to restore my iPhone - would that put it in a boot loop?

    How does one perform a DFU-restore? Are there any good tutorials?

    To perform a DFU restore, plug your iPod/iPhone into you computer and turn you iPod/iPhone off normally. Then press and hold the power button for 5 seconds. Keep holding the power button, and press and hold both power and home for 10 seconds. Then let go of the power button and keep holding the home button until iTunes recognizes it in recovery. However, your screen will be black, unlike recovery mode. Then go ahead and restore like normal from there.

    But if I was to perform a DFU restore; what would happen to the carrier-lock that was present on my device when I purchased it? Would that still remain?

    Edit: And also, is there any risk of fully bricking my phone if doing a DFU restore?
