Planetbeing confirmed iOS 6.1 untethered jailbreak releae in the near future
Hacker planetbeing corfirmed, that untethered iOS 6.1 jailbreak will be relaeased quite soon.
In terms of release date, we're aiming for approximately a week out, but it's possible it will come sooner or later than that.
You can upgrade if you want (I recommend iTunes backup and full restore) but there's no reason to until jailbreak's actually out.
Recently another hacker MuscleNerd tweeted, that utility might be released on Sunday.
