As smartphone sales continue to grow--more than sixty million were sold in 2Q10 alone--a new survey from the Pew Institute shows that most American users of the devices are receiving spam and/or malware on them.

The survey of more than 2,200 Americans by Pew Internet revealed that 57 percent of cell phone users surveyed said they had received some form of spam or malware via instant message, email, or SMS on their mobile phones.

Even so, texting by adults increased to 72 percent from 65 percent since the last survey in September, with 5 percent of respondents saying they send more than 200 text messages a day or more than 6,000 a month. The potential for receiving spam and malware does not seem to be a deterrent.

The survey also looked into trends by age, geographic location, and gender. Our colleagues at EnterpriseMobileToday have the full story.
