AT&T Staggering MMS Roll-out, Pre-Launch Jitters
When you wake up Friday morning, don't expect to see MMS working on your iPhone immediately as AT&T will be systematically activating groups throughout the day, starting at 10 AM Eastern time. Also don't forget that to enable MMS on your iPhone you must first connect to iTunes and download and install an updated carrier file.
That is, if AT&T's network holds up as millions of iPhone users rush to test the new service. That very thought has AT&T feeling extremely nervous right now, according to MacRumors:
blockquote>"early testing has been a little rocky, with AT&T seeing a fairly significant test outage yesterday that has them rushing to beef up their MMSC messaging servers. Estimates among those working on the project are that traffic on AT&T's wireless network will be about 40% higher all day on Friday as iPhone users fire pictures and video at one another."
Guess we will know soon enough...
