????新近一項針對智能手機用戶的調查顯示，美國運營商提供的手機服務質量欠佳。

????40%的受訪者表示每月至少會經歷5次掉話，更有90%的用戶表示因為通話質量太差，他們打算更換運營商。

????不過就這一點而言，并非所有手機用戶都如此。

????不管運營商有多么不給力，蘋果（Apple）iPhone用戶繼續堅守陣地的可能性要顯著高于其它廠商（18.5%，黑莓為15%，Android為14%）。而且，這些用戶繼續使用其手機的可能性也要超出別的廠商一大截（29%，黑莓為17.5%，Android為18.7%，見上圖）。

????這并不令人吃驚。因為多年以來，iPhone給用戶帶來的體驗堪稱完美。

????這項調查是在線調研網站SurveyMonkey在Rebtel的贊助下，于3月6日發起的，一共問卷調查了992位美國手機用戶。Rebtel是一家移動互聯網語音服務（VoIP）提供商，其競爭對手為Skype。所以，受訪者理所當然地被問及當運營商服務欠佳時，他們會怎樣做。

????結果令人吃驚：男女兩方的回答竟截然不同。Rebtel公布了調查數據，具體如下：

????? 相較于運營商的傳統語音服務，男性選擇移動互聯網語音服務的可能性要比女性高出90%（38%對20%）。

????? 相較于運營商的傳統語音服務，女性選擇短信服務的可能性要比男性高出47%（44%對30%）。

????A new survey of smartphone users doesn't speak well for the quality of the cellular telephone service provided by U.S. carriers.

????Roughly 40% of respondents said they experience at least five dropped calls a month, and 9 out of 10 said they'd be willing to switch carriers due to poor call quality.

????But in this regard, not all cell phone owners were alike.

????Owners of Apple (AAPL) iPhones were marginally more likely to stick with their carrier (18.5% vs. 15% for BlackBerry and 14% for Android), no matter how unhappy with their provider. And they were significantly more likely to stick with their phone (29% vs. 17.5% for BlackBerry and 18.7% for Android. (See chart.)

????This is not terribly surprising, given the high satisfaction marks the iPhone has been getting over the years.

????This survey was conducted on March 6 using SurveyMonkey, an online service, which polled 992 U.S. mobile phone owners. It was sponsored by Rebtel, a mobile voice-over-Internet-Protocol (VoIP) provider that competes with Skype, so naturally the respondents were asked what they did when their carrier crapped out.

????Curiously, the poll uncovered a distinct gender difference. As Rebtel's press release put it:

????? Men are 90% more likely (38% vs. 20%) to use a mobile VoIP app as an alternative to their carrier's regular calling service.

????? Women are 47% more likely than men (44% vs. 30%) to use a text messaging service as an alternative to their carrier's regular calling service.
