I was trying to install all those tweaks and mods which I previously had on iPhone 3GS on to my iPhone 4 only to find out that some of the more important and popular apps were still not compatible with the Apple’s latest handset.

Sn0wbreeze 1.7 for 4.0 has been released. Just like PwnageTool 4.0 / 4.01 for Macs, you can now create custom pwned / jailbroken ipsw files on Windows too which can now jailbreak all iOS devices (except iPhone 4) on iOS 4, including iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G. But there is a catch to it! You will need to have their SHSH blobs saved for iOS 3.1.2 in order to successfully jailbreak these devices on iOS 4. Also the jailbreak for iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G on iOS 4 will be tethered, which means whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on.

Also the jailbreak for iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G on iOS 4 will be tethered, which means whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on.

This is going to be yet another userland jailbreak which we talked about earlier and is coming from none other than comex – the developer behind Spirit jailbreak tool for iPhone 3GS / 3G, iPad and iPod touch.

Internet Tethering is a process which allows you to use your iPhone as a wireless modem to share its Internet connection with a computer via USB cable or Bluetooth interface. The iOS for iPhone has this functionality (wired-only) built into the operating system but it is only enabled on selected carriers.
