h3ck34 has been tweeting recently that a PS4 jailbreak device called the USB Whistle will be coming on February 20th with a PS4 CFW arriving no later than a month later on March 20th.
Is it legitimate? According to Wololo: "There are growing rumors that a group affiliated with the Cobra team (a team popular for some of their PS3 hardware mods, and the same team that announced the – yet to be released – cobra blackfin for PS Vita) have been working on a PS4 Jailbreak usb dongle."

While it wouldn't surprise me if the Cobra PS3 scene profiteers started milking the PS4 scene dry instead of releasing open-source freeware, I'm not holding my breath on this rumor being true just yet.
