    If you upgrade to 4.2.1 it will erase all your jailbreak info. You will have to rejailbreak again after the upgrade. Also keep in mind that some of the newer OS's will cause an iphone 3G to run horribly slow.

    Nothing in the new iOS is really beneficial to the 3G...it was left off of every major improvement and feature addition, not to mention the unquestionable performance drop you'll see once you do upgrade to iOS 4. Apple really gave no love to the 3G, and made it to where many users simply became irate over the useless upgrade vs. the performance degradation.

    Not to mention the re-jailbreaking you'll have to do, for essentially no reason.
