When it comes to the wealthy, the higher up you are on the asset scale, the more likely that you’ll be using a mobile device of some kind to stay on top of your financial affairs.

Preliminary results from U.S. Trusts’ annual Survey of Wealthy Americans found that while 32% of respondents (all of whom had more than $1 million of liquid assets) reported they used some kind of mobile device to view their financial information, for those with more than $10 million in investable assets, 52% said they viewed such information.

Perhaps not surprisingly, the younger cohorts in the survey used a PDA or cellular phone to check their finances more frequently–48% under the age of 45; 36% for those 45-54; 29% for those 55-64, and only 19% for those 65 and older. Gender matters in this case, too: on the overall sample, 36% of men reported using mobile devices, and only 28% of women.

There was one other finding of particular interest among the 1,667 individuals who completed the online survey in November 2008: Forty percent of respondents said they used the Internet to communicate with their advisors, and 20% used them to view Webcasts or listen to podcasts from financial services firms.
