    I have a JB 3g that has 3.1.3...

    I'm thinking of upgrading to iOS 4.0 at the least and was wondering if I'll need to JB it again?

    If so, are there any steps I need to take to backup anything prior to the upgrade?

    Thanks in advance

    Yes you would need, but don't do it, you will have a lot of performance problems. Stick with ios 3

    A 3G will run turtle slow on any 4.x.x firmware.
    It does not have the processor speed nor RAM to run any 4.x.x firmware very well.
    But, if you don't care about speed, you can upgrade to 4.2.1 using iTunes

    Dont do it, it will be slow as hell.
    3G iphones should stay at 3.1.3
    But yet if you do update to 4.2.1 you will need to jb again and install all your jb packages.
    Not sure if you also need an unlock or using it on offiical carrier but that would require more steps like making a custom 4.2.1 ipsw etc....

    Thanks guys for all your input...

    The reason I wanted to upgrade was just for that reason, to speed things up cause it seems pretty slow and thought the upgrade would help...

    Any thoughts as to what I can do to check the speed or speed it up?

    Just don't upgrade. It will slow your phone tremendously.

    I put white d00r (sustom firmware) on my iPhone 3G and it ran great. Has most of the newest features, but removes the things that make the phone go slow.

    If you go to http://www.whited00r.com/ and install white d00r firmware, it automatically installs cydia for you as well.

    Lol :D
    Speed things up, you will do the opposite if you go up to 4.2.1.
    In order to speed up your iphone experience get an iphone 4 or 4S.
    The 3G is a dinosaur compared to them and the hardware is outdated.

    I agree that the 3G contains a slower processor compared to the 4 and 4s, however it doesn't explain why the 3G has been slow in comparison to before...

    Any utility to see why its behaving slower than before???

    ----------

    Thanks for the tip Eric...

    Did you try other JB and found this was working faster on your 3g or did you only try this? Trying to see if anyone might have any comparisons and if one operates faster than others...

    Yes it worked very well. I recently got rid of that phone though after I got the 4s.

    I don't know the current version of white door, but I had 4

    Good to know but was wondering if whited00r was the first JB you used or did you use other JB methods and found the whited00r to be best/fastest?

    I've used many methods before. I don't remember about how hard or what the process was for whited00r. The reason I used it was because t he 3G was too slow with the official iOS software on it and it was worth it.
