<p>Thanks but I am still a little confused. We have a Mac at home. My son does not have a MAC at USC. Can you still Ichat at no charge if only one Mac is involved? Also, my son has the AT and T plan for his I-phone whereas we have Verizon at home. Does this make a difference? Does everyone have to be on AT and T to get the text message service? Why do teens like texting so much?
How does it work? Do you need I-chat for the computer and the AT and T service for messaging on the phone? Thanks for explaining this as it is new to me.</p>
