Data-hungry iPhone owners eager to grab iPads can forgo paying for a 3G model altogether and save a good buck. That is, so long as they're willing to take a risk.

MyWi, an app available for hacked (i.e., jailbroken) iPhones, turns the handset into a wireless 3G modem that can be tethered to an iPad. That means you can skip paying the extra $130 on a 3G-only model, along with the $15 or $30 fee for data, and get internet access for free from your iPhone's unlimited data plan, instead.

The process of turning your iPhone into a wireless modem for the iPad looks quite simple. According to AppAdvice, which originally reported on MyWi, all you have to is launch the app and flip the "WiFi Tethering" option to "On." Then, your iPhone will create a Wi-Fi network that you can choose with your iPad.

There is a drawback, of course: Jailbreaking comes with risks. Apple recently issued a support bulletin stating that hacking your iPhone can result in application instability, unreliable voice and data service and other issues. And of course, turning your iPhone into a modem drains its battery pretty fast.

Nonetheless, the jailbreak community has come a long way. The MyWi app looks less cumbersome to set up than an official tethering app we reported on in 2008 called NetShare, which actually made it into the App Store briefly – it was almost immediately pulled and banned by Apple.

The MyWi app can be downloaded through the Rock app store available for jailbroken iPhones. It costs $10, and it comes with a free 10-day trial. For information on jailbreaking an iPhone, visit the Dev-Team Blog.
