Rubicon Consulting published data from an online survey of 460 "randomly" selected iPhone users. Full PDF of results is available from Rubicon. They claim there's a 3.8% margin of error with a 90% confidence interval, but the validity of the data depends on how truly random their sampling was.
Summary of results:
- Email is the #1 function.
- iPhone increases mobile browsing with 75% of iPhone users saying it has led to more mobile browsing
- 50% of iPhone owners replaced conventional (non-smartphones) mobile phones.
- 1/3 of iPhone users carry a 2nd phone

- 40% of iPhone users said "strongly" that they want to add new software apps.
- 40% if iPhone users said the browser has trouble with some web pages they want to visit
