HOW TO: Enable AirPrint on iPhone 3G and iPod touch 2G

As most of you know, AirPrint may be the most interesting feature in the newly released iOS 4.2.1 that allows you to print documents and files directly from your iPhone, iPad or iPod touch. But not all devices will be able to enjoy this function, so we will show you how to enable AirPrint on non-supported devices as iPhone 3G and iPod touch 2G.

STEP 1: Download Redsn0w 0.9.6b3 (Windows - Mac OS X).

STEP 2: Download iOS 4.2.1 original firmware from here.

STEP 3: Connect your device into your computer via USB and launch Redsn0w you download in step 1. Click on browse and point it to the original iOS 4.2.1 firmware of your device and wait while it's recognized.

STEP 4: Now you have to check on Enable Multitasking, other items are optional.

STEP 5: Put your iPhone into DFU mode by following the instructions on the screen:

• Hold down the Power button for 5 seconds.
• Without releasing the Power button, also hold Home buttons together for 10 seconds.
• Now release the Power button but keep holding the Home button for 15 seconds.

STEP 6: Once done, your iPhone will be rebooted and you'll get AirPrint on iPhone 3G ad iPod touch 2G.

From now on, when you open a page in Safari, you'll see the Print button by clicking on the share icon at the bottom. With this option, you can set how many copies of documents you want to copy. You have to select the printer (must be one of the 11 supported printers) and hit Print.

In case your printer is not supported by Apple, you can download and install Printopia to enable AirPrint on non-supported printers. [iPhoneItalia]
