According to our calculations, the progress bar will reach 100% at February 4th, 2013 at 17:00 UTC.
This has also been corroborated by some astute reddit users who noticed that the script is increasing at ~0.0091/min.
It's increasing at ~0.0091/min which would make the release Noon EST tomorrow. (You can see the exact value in the HTML code)
Another confirmation of a 12pm Noon EST release courtesy of Zairex.
I just used Mathematica to calculate the value of all of these variables. As it turns out, when the 0x11c7 value is equal to 1359997200(00) the percentage is 100%. In Unix Time this value is exactly 12pm Noon EST 2/4/2013
EvilPenguin also calculates it out...
The percentage on the @evad3rs website increases by 0.0091 every minute.. 0.0091 * 942M = 8.5%. 942/60 = 15.7 hours 91.5 + 8.5 = 100
Of course, the team could very well finish earlier or run into a problem and need more time to finalize the jailbreak. To be the first to know when the jailbreak is released please follow iClarified on Twitter, Facebook, Google+, or RSS.
