Yahoo IM can be downloaded in a phone, but doesn't allow conferences. My question is if it's downloaded to a tablet, would Yahoo IM be able to open conferences to chat with multiple friends at once?
I am sorry but Yahoo Messenger does not allow conferences on the mobile platform. You can use video and audio but up to 1 person at a time. An alternative for this is ooVoo. The service and application allows you to chat with up to 12 contacts in the same time.
