Hi all, I was finally able to JailBreak my IPhone 4S since the Wi-Fi option become greyed out due to IOS 6.1.3, so I had to mail it in for a replacement which came with IOS 6.1.2, so of course I immediately JailBroke it using Evasi0n. Since then I have installed TetherMe. Which satisfied my need of tethering. I have also customized it to my liking, but for the final touch I would like to install Jelly Lock. But since it is in Beta form I am kind of scared to. I have read that if you mess up your iPhone and can't fix it in safe mode you will need to restore it using iTunes. But if I restore it will have IOS 6.1.3 therefore I can't Re-JailBreak it. So my question here is: Will it be okay to install a Beta Cydia App?? (Jelly Lock Beta).
