Hack Your iPhone 4G

A jailbreak is simply the ability to run apps and use themes and tweaks not approved by Apple. Jailbreaking doesn't slow down your device or use any extra battery. A jailbreak lets your device be how you want it. The news of the iPhone 4 jailbreak comes just days after the process of jailbreaking phones was ruled to be legal by the U.S. Library of Congress. Before that ruling, the legal status of jailbreaking was murky. Jailbreaking an iPhone still can put you out of compliance with Apple's warranty. A well-known hacker on Sunday posted the first "jailbreak" for the iPhone 4. The hack -- available at jailbreakme.com -- installs a program that lets iPhone 4 owners and others purchase apps from stores other than the Apple App Store.
To start the process, visit that website using the Safari browser on an iPhone, iPad or iPod Touch. Unlike other jailbreaks, this version reportedly can be installed from the Web, without the aid of another computer. Hackers already had posted jailbreaks for previous iPhone models, but the jailbreakme.com site is the first jailbreak reported to work with Apple's newest model of smartphone. After jailbreaking a phone, users can download apps that Apple has not approved for sale in its online App Store. Some of the more popular black-market apps include MyWi, which turns phones into mobile Wi-Fi hotspots, and IntelliScreen, which lets users put e-mail and calendars on their home screens.
