I was just on the cingular/iPhone page and tried in both safari and firefox to access the chat feature they have where you can talk to a consultant; both failed. Has anyone been able to use this feature while using a Mac? If so, are you able to do so currently? if the latter answer is yes, then it is likely just a temporary issue, but it sure would be messed up with the chat function for info on the iPhone was not compatible with a Mac.
