Hey guys, I'm sure it's posted somewhere but can't seem to find it. I'm selling my 3G and want to jailbreak it to make some more money to get ready for the newest iPhone rumored to come out soon. My question is what are my options for jailbreaking my phone with the most up to date OS? I want to back up my phone on my macbook to save all my data, then use my windows PC to jailbreak. I know there are different jailbreak softwares but have no idea what the differences are. I mine as well unlock it for other carriers while I'm at it. All feedback will be appreciated!
