LG420G cost of call
 

I just bought the LG420G and wonder if someone could answer the following question.
I pressed some button on the phone (don't know which one) and it said you have been charged $1.00. What call/app would have cost $1.00?
I know to access the browser it costs .50 cents, but don't know what would cost $1.00.
Does anyone know, so I don't click it again?

Please advise and thank you.
