Ok, my I have a question, and let me know if its worth it or not. I have a 4.2.1 jailbroken Ipad via greenposi0n/redsn0w. I never really plug my ipad into my MAC, just use wall charger when I need to. Everything is downloaded via cydia/app store.
I have SHSH blobs saved 4.2.1 (via) cydia---> "make my life easier".(tab)
Is it worth upgrading to 4.3.1 and then rejailbreaking untethered 4.3.1 or just leave my ipad at 4.2.1 untethered jailbreak?
