In the poll conducted by Piper Jaffray, 53.3 percent of consumers said they expect to buy an iPhone 5 in the near future. That's about consistent with 54.9 percent who chose the iPhone 5 in October, and still a bit higher than 47.7 percent who said they'd choose Apple in September.
"We believe this is a positive that demonstrates the majority of U.S. consumers want an iPhone 5 even following the launch craze, and despite the Maps issues that have been widely noted," analyst Gene Munster said.
The latest survey found that while more than half of U.S. customers planning to buy a smartphone will choose Apple's iPhone 5, 35.3 percent of respondents said they will choose a device that runs Google's Android platform.
As for the remaining smartphone players, 6.5 percent of those polled in the latest December survey said they are planning to buy a Windows Phone in the near future, while 4.9 percent are eyeing a new BlackBerry.
Piper Jaffray also conducted an analysis of what users are talking about on the social networking site Twitter. The investment research firm conducted a search for tweets that contain the keyword iPhone in addition to related words like "bought," "shipped" or "purchased."
Based on its searches, Piper Jaffray believes that purchase trends for the iPhone 5 are ahead of those for the iPhone 4S. The company's data found that about 2.5 months after launch, the demand index for the iPhone 5 is up between 30 and 40 percent over the iPhone 4S, based on Twitter posts.
