Make Personal Conference Calls on the Fly with your iPhone

We are working through a family issue that requires me to keep a number of family members up to speed on changes.  I found the easiest way to do this is to quickly call all the right people and have one conversation where we can all ask our questions and share advice – just like at work.
An easy way to create a quick conference call is to simply use your iPhone to add additional callers to the conversation.  Just click “Add Call” during your call and then “Merge Call” to add the additional calls to the group conversation.
You can add up to five callers if you have AT&T or T-Mobile service and up to two callers on Sprint or Verizon.  This limit is based upon your service provider – not the service provider of those you are calling.
