I will say that I'm going to stop at both my bigger T-Mobile locations today (got too many retailer locations but doing the corporate stores only) and see if I can find some extra details from them.
Corp rep from the desk of j.l. Did say that they will have some stock in stores for walk in. Just no extra details due to each stores stock.
I'm hoping to call the local corporate store later and see if I can get any info at all as I'll be there bright and early tomorrow hoping to get lucky.
