Still on firmware 4.1 on the iPhone4 and untethered jailbroken with limera1n. My battery life is great and everything feels just as smooth & quick as a non-jailbroken iPhone.
I also have Winterboard loaded. If it does eat battery life, then it has never been noticeably to me.
Personally I would never even attempt a tethered jailbreak, which is why I will probably never update until there is a confirmed untethered version available.
