The iPhone is back! Anna Wintour upgrades her cell after she was spotted with a $15 flip phone

Anna Wintour sparked confusion after she was spotted carrying a rather dated looking flip phone last week, but it appears she has traded it in for something more modern.

At Carolina Herrera's New York Fashion Week presentation on Monday, the Vogue editor was pictured sitting in the front row clutching a Starbucks cup in one hand and an iPhone in the other.

The 64-year-old fashion maven attended the show in a feminine floral dress and her favorite nude slingbacks, keeping warm with a yellow cardigan draped over her back.

The mother-of-two had people convinced that she was lagging in modern technology when she was pictured using an out-of-fashion flip phone at the U.S. Open in New York on Thursday.

She peered out from her signature dark sunglasses to look more closely at the tiny screen on the phone, which looked to be a $15 pay-as-you go phone from AT&T.

But judging by the photos of her today using a much more up-to-date gadget, it appears she may have a whole collection of phones to pick and choose from.

Perhaps she was saving the photo space on her iPhone for snapping pictures at Fashion Week.

The flip phone model she was using, an AT&T Z222 GoPhone, has a small two-inch display screen and offers texting and calling but no apps.

Her decision to use such a simple and inexpensive was something of a surprise considering Ms Wintour presumably has the most cutting-edge products at her fingertips.

Perhaps the editor, who is known to be a creature of habit, simply likes to stick with what she knows best.

Indeed, back in 2004 she was seen using a similar flip phone while watching a Michael Kors runway show, although that particular model looked even more retro with an antenna.

By 2007, she graduated to a somewhat sleeker model - the Motorola Razr, which she brandished proudly at yet another fashion show.

From 2009 to 2012, Ms Wintour was pictured multiple times using a Blackberry, and it seemed she had finally found a modern phone she liked.

And just last year, she was seen carrying around both a Blackberry and an iPhone, a symbol of her busy business life.

So it's a mystery as to why she would have downgraded back to a flip phone to watch the tennis this year.

Sitting next to Hugh Jackman at the match, Ms Wintour looked typically chic in a floral patterned dress and maroon cardigan, her hair styled in her usual sleek bob.

The usually steely mother-of-two let her guard down to cheer excitedly for the tennis players, throwing her fists in the air and smiling at each exciting moment of the match.

The lively experience was likely a welcome break for Ms Wintour, who had been busy preparing for New York Fashion Week, which officially began on Thursday.

As arguably the most respected editor in the fashion industry, she has been observing many of the big shows from the front row.
