I have a JB, fully unlocked OTB 1.1.2 iphone. I want to upgrade to 1.1.3/1.1.4 while still keeping my installed apps and other settings. Is this possible? Also, what is the best way to upgrading from an already jailbroken 1.1.2 iphone to 1.1.3 or 1.1.4 JB?

I have been checking out Ziphone 2.5 program, and want to know if there is a downside to downgrading your bootloader from 4.6? Does the iphone become unstable or get any bugs from it?

Thanks for all the help guys
