Yes, DevTeam released new version of their software. First of all, please, do NOT use unofficial software from unknows sites (f.e. quickpwm.com). We recommend to download from torrent or official mirors.

We regulary publish latets software and firmware links. Use them or the same ones from DevTeam site.

So:

• iPhone 2G and iPod Touch: update to 2.2.1 with iTunes and run QuickPwn to jailbreak, activate and unlock you device.
• iPod Touch 2G: sorry, you need to wait a bit more
• iPhone 3G + NO UNLOCK: If you do not need unlock, you are using your iPhone with one carrier or you hae factory unlcoked iPhone, just restore or upgrade to 2.2.1 using iTunes and use QuickPwn to jailbreak and add Cydia and Installer.
• iPhone 3G + UNLOCK: you need to preserve current baseband software. Preserving the baseband will ensure that you can still use “yellowsn0w” the iPhone 3G unlock application. To upgrade your phone to 2.2.1 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.1. PwnageTool is only available for Mac OS X.

DevTeam updated yellowsn0w to version 0.9.7 to work with modified (!!!) firmware 2.2.1, in which you preserve old baseband from firmware 2.2.

Thanks to Dev Team and the porting work of Jay Freeman as well as the authors of 3Proxy, it is now possible to “tether” your iPhone 3G and use its Internet connection on your laptop.

Warning – Tethering your iPhone is against the iPhone data plan terms. AT&T could slap you with huge fees if you overuse this. I recommend only using it during emergencies.

Here is a basic plan (by the way, this should work for old IPhone also):

• Jailbreak your iPhone 3G
• Install 3Proxy and Terminal
• Create an ad-hoc Wi-fi network using your laptop
• Join the network with your iPhone
• Find the iPhone’s IP address
• Open Terminal and run the proxy program
• Open Safari on your iPhone and open a web page
• Configure your browser to use the proxy

Later we’ll discuss it with more details.

Step 1: Jailbreak your iPhone
