According to @redsn0w_testers, RedSn0w 0.9.7b4 will be released today.
Today’s beta4 will eliminate separate usbmuxd process (so many more Mac users can use it). After that, expand to Windows.
This is the 4th beta of the new “backup method,” which redsn0w calls “Jailbreak Monte.” Currently, this jailbreak technique disables bluetooth and there are reports of problems with Skype, which just launched video calling support on the iPhone.
