Users of Apple's iPhone are using the device to do everything but talk on the phone, according to a new study, transforming the product into a mobile entertainment platform rather than just a cellular phone.

Owners of competing products - such as Nokia's N92 or Research in Motion's Blackberry - use their phones for voice communications 71.7 percent of the time market researcher, iSuppli discovered, while iPhone owners spend just 46.5 percent of their time with the product engaged in voice calls.

"This usage pattern shows Apple has succeeded in producing a true convergence product that consumers like to use for multiple purposes," said Greg Sheppard, chief development officer for iSuppli.

I hardly ever used it to talk on the phone.
