With all the iPhone and refarming news we’ve seen come out of T-Mobile in the past few days, or really come through us in the past few days — our curiosity is again piqued as word drops that T-Mobile is holding “all hands days” from September 21st-24th. Coincidentally, these are the same days that AT&T and Verizon are both rumored to have employees working with the release of the next iPhone.

Given that our most recent bit of information has us almost 100% sure T-Mobile won’t be picking up the next-generation iDevice, what exactly ARE they planning for this future Friday, Saturday and Sunday. It’s certainly possible they could be planning a marketing campaign against the release of the iPhone, with an emphasis on their unlimited plan, Android lineup and 4G network, but we’d be naïve to say if anything could really overshadow the launch of a new iPhone.

On a separate note, it’s possible T-Mobile is doing something with the launch of another device this day, or maybe it’s not a device at all. Perhaps there is a bit of refarming news dropping this day or perhaps we’re completely off the mark and we have no idea what T-Mobile wants these days blocked off for.

We do know one thing however, whatever this is, we’re eager to find out more.
