iChat sending multiple SMS messages
So, I've been using iChat since it first came out and haven't really noticed any odd issues until recently ...
For the past 4 days, when I send SMS messages to someone from iChat, some of the messages will be received by the person multiple times, even though I only sent them once.
It seems that this happens when I receive these automated messages right away:
Auto-reply: Your message could not be delivered. Please try again later.
Auto-reply: Uh-oh! That number won't work. Please make sure it's a valid US mobile number from a supported provider, and not a landline. Need help?
But yet, I don't have this problem when I'm using the AIM service through iChat, so I know this is an SMS issue.
The person who receives some of my SMS messages multiple times contacted his cell phone service provider, and they said that they "reset things", but yet the problem is still happening.
Any ideas?
