    I can only advise you on this, the latest version for the 3G is 4.2.1 and that doesn't even allow you install the latest apps and games, my sisters is a 3GS running 4.3.5 and it doesn't allow you to install the latest.

    Sources: my 2nd gen ipod touch is running 4.2.1, and that's the max, so I'm assuming that's the 3G too.

    Just plug it into iTunes. Then it will ask to download and update. Do that.

    WARNING: This may disrupt your unlock and jailbreak, I am not a whiz about this stuff. Another member will probably assist you further, I just provided the way to update.

    I have jailbroken and unlocked my phone myself before without using jailbreakme.com. It is difficult but very possible, however, I don't think you will get anyone to explain to you exactly how to do it simply because it's hard and many steps. I can give you some vague information that will help and some advice. Just to note I'm not great with computers and I now know a guy who does everything for me for 20 bucks. If you can find someone like that it's way worth it.

    Do NOT upgrade your phone through iTunes. It will not only unjailbreak your phone but will load the latest iOS onto it which would be tethered jailbreak and very difficult to do. You will have to search for a newer firmware and download that to your computer. Through a series of steps you can update your phone with that new firmware. I recommend just getting iOS firmware 4.1. It runs far smoother than any newer firmwares.

    I disagree with the fellow that said you need a new phone and the newest firmware. There are some things you may not be able to run and apps that require newer firmware, but you probably won't even notice it. Also, the jailbreak, in my opinion, is far more valuable and important than the few apps that won't run on 4.1. In fact, you may even be able to find the same app that can work on your firmware through xxxxxxxxxx or cydia.

    Anyway, in order for you to learn how to upgrade your firmware and rejailbreaking or keeping the jailbreak, I recommend doing some research and find a good YouTube video that has good rating and comments on it working. A reliable website that gives a step by step guide would work too. If you start researching, you will find it.

    Good luck! ^_^

    You need to preserve you baseband to facilitate an Unlock on your 3g iPhone use tools like TinyUmbrella to do this.
    Only then can you update to 4.2.1 firmware...then jailbreak with using whatever method you like.... would recommend finding a good YouTube video for you to follow

    Just a word of advice don't pay to unlock it , all jailbreak and unlock programmes are free and the same you would pay for .

    There is the Jailbreak section of eiC that has a TON of info in it & a lot of very smart people that can help out. You can not access it from the app, have to use the full web version.

    I can not even install cydia basic apps it says not compatible, so I definitely need to upgrade my iOS from 2.2 to atleast 4.1 , I don't know what do you mean by base band , I see modem firmware is 02.28.00 is that the one? I still not sure how to upgrade my iOS . Is it like any tool I use to upgrade iOS will lock my phone and then I need to unlock using some other s/w? I could not find a youtube video which tells me how to upgrade exactly unlocked/jailbroken 3G 2.2 firmware to latest (at least 4.1) any help pointers is appreciated
