Re: [Skunkworks] Fault in $afcom's billing system? Bug?

When surfing, you are doing what is known as a data call! You can call and surf at the same time but that is limited to the phone model you have. If it can handle 2 or more threads (processes in Desktop world) at a go then you are good to go but if it cannot then the data call is 'paused' till the voice call is through!
