Update: ABC News reporter Lara Setrakian tweeted 8 hours ago: "Cell phones coming back on line in Egypt, internet still seems to be out as of an hour ago."
It's unclear whether BlackBerry service has been restored to the rest of the country, or if it's still functioning now, but Engel said of the restoration of BlackBerry service and its effect on the widespread unrest in Egypt, "I don't think that's going to fundamentally change the equation, but it is showing responsiveness."
Engel said while BlackBerry service had been restored, he added, "I haven't had a chance to check the Internet, but I assume that's back on, too."
