charges applied? My AT&T Phone broke and I had a T-Mobile G1 laying around. I got an unlock code and I inserted my AT&T Sim card into the phone, inputted the unlock code and now everythings working smoothly. My question is how are my rates going to apply? Will I get charged for using the internet? What happens when I buy an app? On my old phone, I only had 200 texts a month, is this still the same? THANK YOU!
