GRRLS AND THEIR SMARTPHONES DEPT.: She’s a bona fide comedy genius,  but TINA FEY’s a total techno-dork!

Dining with pals at SUR Lounge in West Hollywood, the multitasking writer/producer – who’d been talking on her new iPhone to people she works with, husband, kids, etc. – got all shook up when the damn thing suddenly started making unintelligible sounds, and she couldn’t silence it.

“Embarrassed in front of her guests, Tina ran outside, finally got the phone turned off, handed it to the valet and told him to hold onto it for her,” said a friend.

“An hour later, she left SUR Lounge and had driven a few blocks when she remembered she hadn’t asked for her phone.

"So she drove back, asked the valet for it and was told, ‘Ms. Fey, I put your phone in your glove compartment, as you’d asked.’

Embarrassed a second time because she’d completely forgotten her instructions, Tina rolled her eyes, apologized, tucked two $20s into the valet’s hands – and drove off feeling dorky!”
