Basic MMS SMIL Tutorial

A recent thread on the NowSMS discussion board made my head hurt:  MMS: first shows a picture and then the text It started off simple enough.

iPhone MMS Message Send Failure on GPRS and EDGE

We’ve recently investigated a problem reported by a NowSMS MMSC customer where iPhone 4 users were reporting a high volume of failed MMS message sending.
