In a big shift for the phone industry, women have emerged as eager buyers of not just iPhones but of all so-called "smartphones" - BlackBerrys, Treos and other models.
In the past year the number of American women using smartphones more than doubled to 10.4 million, growing at a faster pace than among men, according to Nielsen Mobile, which tracks wireless trends.
The trend is mirrored in sales of the iPhone. In October, nearly one out of four owners of the iPhone was a woman, according to Nielsen. By March that number rose to one in three. The iPhone model announced Monday, with faster Internet access and mapping features, may accelerate the shift.
Smartphones are cheaper now - as little as $99 for the petite BlackBerry Pearl - and are better designed. Women have been using them for years in business, of course, but many are finding that the phones can also help manage their families' time-pressured schedules and keep them in touch with friends.
"You are not seen as a geek anymore if you have a smartphone," said Carolina Milanesi, research director at Gartner Group, a research firm. "Women, including wives and mothers, need to keep track of their busy lives, too."
The phone makers and service providers increasingly see women as the path to the entire household.
According to Verizon Wireless, 71 percent of women make the decision about their family's wireless choices, including phones and service plans. (Smartphones require data plans that can cost $30 or more a month.)
As a result, smartphone makers are beginning to market specifically to women. Research In Motion Ltd., based in Waterloo, Ontario, has taken out ads for its BlackBerry phones in Elle, Martha Stewart Living and Oprah Winfrey's magazine O.
David Christopher, the marketing chief of AT&T; Inc.'s wireless division, said women were less likely to be wowed by fancy gadgets. Instead, as smartphones have become sleeker, smaller and cheaper, they have become more appealing to them.
"Now they are small enough to be in your purse or pocket," Christopher said. "Design does matter."
Competitors have been working hard to catch up to Apple Inc. in the design department. This month Sprint will begin selling the Instinct, a touch-screen device created by Samsung that shares many features with the iPhone. And this summer RIM is adding the BlackBerry Bold, which, like the iPhone, runs on a faster mobile network.
Nielsen's research shows that women are more price-sensitive than men and half as likely to care about whether they have used a specific brand before. Still, more traditional pitches do have their own appeal. RIM and Verizon Wireless were successful last Valentine's Day with promotional events for a pink BlackBerry Pearl. Even then, picking the right hue was tricky.
"We picked a shade of pink that fit in all kinds of settings - not too flashy," said Mark Guibert, vice president of corporate marketing at RIM. "It was the only color that was purely driven by the female audience. Years ago the market was much more focused solely on function. Now there is more focus on lifestyle."
It's about time, said Milanesi, the research director. When she used to attend mobile trade shows with a male colleague, she said, "they showed him the cool phone and showed me the phone with a mirror."
"Companies need to be careful to not think that to sell smartphones they just need to be pink," she said. "There are other things women want."
Steven P. Jobs, Apple's chief executive, understood this when his engineers created the iPhone. Although it is not marketed specifically to women, it has a clean design and multimedia features that many women say they like but that the BlackBerry lacks.
Kayne Lanahan, who lives in New York and is the owner of an online music site, bought an iPhone in October after her dog wagged its tail and tipped her Nokia cell phone into a cup of coffee. She didn't even contemplate a BlackBerry, stung by the image of the work-obsessed executives she knew when she worked at News Corp. who furiously e-mailed their bosses during meetings and at the table during late dinners.
"I didn't want to be that person," Lanahan said. "This is such a girly thing to say, but I love the iPhone's design."
That, and the fact that the $399 device suited her technological lifestyle. Lanahan owns an Apple MacBook Pro laptop and five iPods. She uses the iPhone's notepad function to track restaurant recommendations from friends. She takes pictures at concerts, some of which show up on her Web site.
And once, when her name didn't appear on the guest list at a club she was invited to, Lanahan used her iPhone to show the bouncer an e-mail which proved she was invited.
Plenty of other women are finding that smartphones are much more than a tether to the office. According to Nielsen, two-thirds of women with smartphones say they use them primarily for pleasure rather than business. The contrast with men is stark: Just 42 percent of male smartphone owners say the same.
