I registered to all but confirm that Metro will be releasing the S3 on the 28th (this Friday). When specific markets may get it will vary I'm sure. I called customer service, wanting to confirm that corporate stores would have it. They gathered all of my information, wanted to know where I got that information, put me on hold for like 15 minutes, then the rep fumbled around with...
"I can't confirm that information. However, if you check the MetroPCS.com website on Friday, you'll be able to see if the phone is available or not."
Lol.
