As pointed out by Twitter user @Pix3lDemon, the new website for jailbreak tool evasi0n strongly hints at a Sunday release. Although we have guessed out something from members of the evad3rs themselves, which have hinted at a Super Bowl day release, it does reafirm the belief that Sunday. It's still great to figure out that!
As you’ll see on the evasi0n.com splash page, each device that shows a visible Calendar icon is displaying a ’3′. It just so happens that the first Sunday in February is on the 3rd. Coincidence? Probably not. Check past the break for the screenshot.
