I have a NON-jailbroken (4.2.1) iphone4 that I would like to jailbreak (got a replacement iphone that came with 4.1). I have a backup of my phone on my computer, I don't want to lose any of my game data as countless hours have gone into them. I was wondering if this was possible because the phone was not jailbroken prior and don't have access to ssh.
please help me out! thanks.
