Update: It turns out this was a fake update and didn’t come from Comex.
Jailbreaker Comex teased his Twitter followers by temporarily posting the above image to his Twitter stream. Shortly after posting the image, Comex took it down.
The image would seem to indicate that a Jailbreak for the iPad is set to be released at the fairly exact time of 6:17:11 GMT. It is not known if the reason for taking down the image is due to a delay, but either way, in a little over 3 hours time we will know what “This is big” actually means.
