I jail-broke my 3GS using GeoHot's
Blackra1n a few weeks ago and installed
Winterboard without a hitch. But some unrelated software issues required me to restore my iPhone using iTunes yesterday. No problem. I restored, and used
Blackra1n to jail-break it again. But this time, when I tried reinstalling
Winterboard my iPhone hung up on the boot screen. Nothing I did seemed to work so I restored it again, jailbroke it again, reinstalled
Winterboard.
Nada.
I was pretty sure Apple hadn't somehow figured out how to spike my iPhone so it couldn't use themes, so I back-tracked and decided to replicate everything I did the first time and see if I was doing something to cause
Winterboard to screw the pooch.
As they say, third time's the charm. The only thing I did differently the first time was I installed
MobileTerminal and
OpenSSH before I installed
Winterboard because I wanted to change the default password ASAP. Following those steps (and changing the password in the process) I was able to successfully install Winterboard
after I'd installed the two other packages. Reading through this thread I discovered
Zaius55 had to do something similar with his 3G. Don't ask me why it works, but it works.
When Jail-broke iPhone's are outlawed only outlaws will have Jail-broke iPhones.
