    I finally got my 3G unjailbroken. Unfortunately I think it actually runs slower running iOS 4.2.1. Now I have disabled the Spotlight, cleared my icons, and done the "dead reboot" several times, but it is still quite hesitant.

    Should I just jailbreak it. Is there a specific jailbreak that is lighter and quicker than some others. All really use is Facebook anyway. I'm used to my dad's lightning fast iPhone 4 :(

    Jailbreaking an iPhone 3G running iOS 4.x will make it slower.

    Many claim that iOS 3.1.3 was the last OS for the iPhone 3G that worked for them (fast), and I thought I read somewhere that Apple was allowing iPhone 3G owners to downgrade their device back to iOS 3.1.3, but I'm not 100% if thats still possible.

    Try Whited00r. It helped my aging first generation iPod Touch seem a tad bit faster. Granted your 3G won't become iPhone 4 fast, but you'll get some nice IOS 4 features which should run slightly better than it currently does.

    At the iPhone hacks section.
    Go down to 3.1.3
    But even on that an iphone 3G feels like a snail if you used a 3GS or iphone 4 before.

    Downgrade your iPhone 3G to 3.1.3... Trust me, I did it months ago. It's far better now ;). Before that I tried a lot of things like you but it was always slow.

    As for the 3.1.3 downgrade, what am I actually going to be losing from a functionality standpoint from 4.1.2.

    The applications support is the only thing I miss. Some apps don't have iPhone OS 3.0 compatibility like voip and video recorders ones. Say goodbye to Google+ app if you used to use it. Say goodbye to folders too.
    But I prefer to have 3.1.3 without some applications, because I was attempted to throw it out of the window when it had 4.1.2... It was too slowly!
    Backgrounder is better than native background because I choose apps I want to have in background: iPhone 3G has only 128MB of RAM.

    Well... All I have to say is WOW. I can't believe how much quicker it is lol. It does look a bit old school with the home buttons/dock and the Earth logo haha. But Thanks for the help everyone!!!
