Well, instead of trying to jailbreak, I signed up for dev license, and got myself iOS 5! Well worth it, love the new features, and Beta 2 is completely stable for me.
Of course it wouldn't be me without a scary moment - when installing the new firmware, for some reason my phone went dead. Upon disconnecting it, I could not get it to turn on at all - power+home didn't work, plugging a charger didn't work... Called Apple, after few minutes of trying I got a case # and was supposed to get a new phone at the Apple Store. As soon as I hang up, I connected it to my MBP to try to revive it one last time, and low and behold, the phone was in recovery mode even though the screen was blank. Anyway, it's working great, and I highly recommend iOS 5! It will be a fantastic upgrade.
