    the actual process of jailbreaking and having the cydia will not slow down your phone whatsover. Depending on what you install after can indeed slow down preformance.

    The jailbreak is a work in progress, but I have not read of any exploit for the new 4.1 baseband. So, who knows about an unlock.

    So for 4.02 users, is there a specific way to upgrade to 4.1 to ensure a future successful jailbreak?

    Not really, you just upgrade to 4.1.
    Unless you care about maintaining your unlockable baseband on your i4.

    There is no reason to rush into an upgrade.
    If you can't wait and will need to unlock, be sure to use TinyUmbrella to update your iPhone 4 keeping your current baseband.

    4.1 installs a new as yet unlockable baseband.

    I just received an replacement iPhone4 from an Apple Retail Store. I figured I was screwed until the rep told me to update my phone when he handed it to me.

    Fat chance!

    Ok I had 4.0.2 jailbroken, and checked the "make my life easier" on Cydia. I restored my phone and upgraded to 4.1....is there any I can go back and jailbreak my phone again?

    Since 4.0.2 can not, at this point, be jailbroken yet, I assume you mean 4.0.1.

    That being said, yes, you can downgrade a d jailbreak. Unlock, not as of this moment.

    Ultrasn0w unlocks all basebands except the new 5.14.xx baseband installed by 4.1 firmware.

    The newest jailbreak will JB 4.0.1, for your iPhone 4 but not 4.0.2 or 4.1

    If you update your baseband, you cannot downgrade it on an iPhone 4

    Only if you have hashes saved for those firmwares.

    If you don't know what hashes are, Google "SHSH" and do some reading.
    Also, Google "Caching Apples's Signature Server" and read that.

    Just wait for 4.1 to be jailbroken, if you need to unlock do not upgrade to 4.1 using iTunes, use TinyUmbrella, but wait for the jailbreak to be released.
