Is anybody using the ONE.AT EMail service with the iPhone?
Although all GPRS traffic from and to should be free of charge, the invoice shows some kilobytes of transfer and therefore ONE is charging me a few bucks.
I called a service representative and he states that some smartphones are producing overhead traffic before connecting to the mail servers.
Is there any possibility the iphone generates some kind of "suspicious ghost traffic" before it's checking for new mails? (Maybe the phone is "calling home"?)
