UPDATE 10:03 AM: Apple stock is blowin' up -- it's now up 4.00 a share.
UPDATE: Jobs' return seemed to be noticed on Wall St. -- right now (9:35 AM EST), the Apple stock is up 2.52 a share. Steve Jobs is back to an Apple a day -- and we've got the proof.
TMZ obtained this photo of the Apple co-founder leaving company headquarters in Cupertino, California around 3:00 PM Wednesday.
It's the first time we've seen Jobs back in action since January, when he took a leave of absence for a liver transplant. Jobs has reportedly been back at work for about a month.
BTW -- this photo was taken on an iPhone.
