I asked this once before (in another thread, kinda hijacked it) so I thought I would give it it's own thread. I have a 4s thats on 5.0.1 (9A405) and 1.0.13. I was told to keep it at 5.0.1 instead of 5.1.1. Why did we wait for 5.1.1 for jailbreak for the 4s? This is to unlock for tmobile. So at this point what are my best options for using this phone on tmobil? Jailbreak at 5.0.1 and unlock, or upgrade to 5.1.1 and unlock? I realize that the unlock is unstable with 5.1.1, but has something changed? So this brings me to figuring out if I need to save the SHSH blob before upgrading (if I really need to upgrade this phone). I cant get tinyumbrella to install, seems to be java issues, I'm working that issue out in the mean time, thanks.
