Since Apple first released the iPhone 1st Generation in 2007, the iPhone Dev Team has been hard at work producing free jailbreaking software for the iPhone 4 and other models. Here is a list of the most popular free programs for unlocking iPhone 4:

• Limera1n – This is used for jailbreaking iPhone’s with popular basebands that are able to be unlocked with the PDF exploit. Jailbreaking with limera1n is a tethered jailbreak that only works for iPhone 3GS models
• Redsn0w – The dev team’s most successful jailbreak tool is by far the redsn0w app. It is used to both jailbreak and iPhone 4 unlock baseband 2.10.4. Redsnow hasn’t been used however with newer models due to its high risk of disabling iPhones
• Blackra1n – George Holtz created blackra1n and blacksn0w and was the first to answer the question of can you unlock iPhone 4. Blackra1n is only able to unlock Baseband 5.14.02 which is why it this jailbreak tool is not for updated iPhone models.
• TinyUmbrella – This program is used to modify custom IPSW firmware files for your specific phone setup. Typically it is used in conjunction with Ultrasn0w 1.2.
