Here is a download links for iPhone OS 3.1.2. I know that this is not the latest firmware but I think everyone should have this files.
You can find full list of iPhone firmware (1 to 3) here.
Few hours ago Dev-Team released their new PwnageTool that can jailbreak iPhone OS 3.1.3. Unfortunately this version can’t jailbreak iPodTouch 3G nor iPhone 3GS!
iPhone 3GS users still be aware to update to this new version of OS (3.1.3), if you update accidentally like me you have to wait until the next releases of Dev-Team tools.
You can find the whole article here at Dev-team Blog.

Once again Alex posted some useful stuff about developing for a jailbroken iPhone. Below you can find it! Vital stats:
Let’s do it.
UPDATE: Corrected a problem with the run script build phase: corrected the directory names for the new version and copied the new phase that doesn’t include “resource_rules.plist.”
The Goal: we want to be able to click “build and go” in Xcode and get the app we’re working on to load to the phone and start up. More than that, we want to be able to DEBUG on the thing!
Abstract: Our methodology is slightly different this time around. This time we’re going to tell Xcode that it doesn’t need to codesign for iPhoneOS targets, then we’re going to tell it don’t codesign for iPhoneOS targets, then we’re going to tell it, well, actually, codesign but do it using our script, not your built in method.

If you want to use Appsync (installd, mobileinstallation patch, etc) on your iPhone you should wait for Dev-Team to release their new tools that support OS 3.1.3. I highly recommend you to wait…
Apple today released a new version of iPhone OS. This update contains 3GS baseband upgrade (05.12.01) so BE WARNED. DON’T UPDATE YOUR iPHONE 3GS.
There is not any notable change in this firmware.
iPhone 2G users : Can use redsn0w (download here) in order to jailbreak it. Please note that you should have firmware 3.1.2 file and you must point redsn0w to that files after updating (or restoring) to 3.1.3.
iPhone 3G users : If you need to unlock your iPhone baseband (using ultrasn0w, etc) DON’T UPDATE TO 3.1.3. otherwise use the above method.
iPhone 3GS users: BE WARNED. DON’T UPDATE YOUR iPHONE AT THIS TIME.
iPod Touch 1G users : Same as iPhone 2G.
iPod Touch 2G users : Do not update to 3.1.3
iPod Touch 3G users : Do not update to 3.1.3

With the releases of iPad Apple shown up a new OS to developers. iPhone OS 3.2 only support iPad as they said.
Initial support for the newly released iPad Initial support for landscape springboards Includes new frameworks for recognising custom gestures, custom keyboards etc. Allows display output to an externally connected display for compatible 3rd party apps Allows user to change home screen background At this point, only applicable to the iPad and not the iPhone
Apple released their new tablet named iPad. As rumured it has a large (9.7 inch) multi touch screen, 1Ghz apple custom processor.
Actually there is nothing new because we see all these technologies in our iPhones. iPad has the same UI (as you see above) as iPhone. I think that apple made a big mistake by releasing iPad. They should work more on the UI, hardware, etc. There is no camera, no USB host, no more storage, … just 10 hours battery. Shame on you Steve!
Dev-Team released the new version of redsn0w that support iPhone OS 3.1.x.
You can download it here:
How is it different from PwnageTool? redsn0w doesn’t require a system restore like PwnageTool does (it doesn’t even use iTunes at all). On the other hand, PwnageTool can prevent your baseband from being upgraded when you upgrade your firmware, preserving your unlock. (redsn0w doesn’t touch your baseband but it doesn’t help preserve it during an upgrade either). redsn0w works by modifying your current filesystem, so your existing baseband, data and applications should remain intact. How is it different from blackra1n? - It uses our original Pwnage bootrom exploit for iPhone 2G, iPhone 3G, and iPod 1G. (Because it’s a bootrom exploit, it can’t be fixed by Apple without a new hardware release.) Note that redsn0w 0.9 does use the USB exploit for iPhone 3GS and iPod 2G running 3.1.2, but that exploit will be fixed in Apple’s next FW release. - It offers custom logos and verbose boot - It installs Cydia without needing a separate download - It’s not as fast (but redsn0w handles more variations)

It seems that Apple wants to release the new version of iPhone OS. iPhone OS 4.0 will be avabilbe only for 3G & 3GS versions of iPhone. It’s very bad news for who already have their original iPhone 2G like me!
In this guide I want to help you to choose the right firmware for your device with the speed in mind. I already test all firmware from 1.1.4 to 3.2.1 (the latest firmware as I write this article) on my iPhone 2G.
The speed factors are as below:
1.x
There is nothing to say about 1.x family because there is no AppStore on this family, So JUST FORGET IT!
2.x
If you remember the early versions of 2.x family (2.0, 2.0.1, 2.0.2, 2.1) is full of bugs so everyone decide to upgrade to newer version as soon as Apple release them. But by the releases of 2.2 the game changes. It’s stable, fast and accurate in action and also if you jailbreak it, it will bring all the good things that you need to enjoy your iPhone such as AppStore, Copy/Paste (clippy), Video recording (Cycorder), Bluetooth file transfer (iBluetooth), Background application (Backgrounder), etc.
3.x
The main feature of OS 3 is the “Push notification”. Actually there is no more notable things in this version (you can find full list here), all the things that they add to this version was previously resolved by jailbreakers. Beside that if you have to unlock your 2G using any kind of PWNing tools you will lose the Push ability, after that you will found a way called “push fix” by Dev-Team that bring push to your 2G but when you enable it, first of all your device will works very slowly and also you will get lots of false push alerts. The speed impact of the 3.x family on 2G was very ridicules, I think Apple intentionally do this in order to force 2G users to buy an iPhone 3GS. It may also happens because of jailbreaking.
Conclusion
If you want to have a fast iPhone 2G I suggest you to use OS 2.2 (if you already upgrade to 3.x you can easily downgrade it, i will post something about that in near future).
If you upgrade to 3.1.2 :
If don’t upgrade to 3.1.2 (stay on 2.2)
