Looks like iOS 5 is going to make life very difficult for jailbreakers.
This is a huge bummer, though iOS 5 is giving me fewer and fewer reasons to jailbreak. (I even paid for tethering this month while traveling. What?!)
From Ars: "Those who have already backed up pre-iOS 5 blobs will still be able to restore their phones to them, but only using an older version of iTunes. And jailbreaks will likely remain a part of iPhone culture, but they will probably be limited to tethered jailbreaks—no more wireless jailbreaks for you."
Will this affect you? Do you think the dev team will eventually find a way around it? I've spent quite a bit of money in the Cydia store, so it nearly renders all those purchases useless for me. Kind of annoying, but it's a risk I knew I was getting into.
