IM starting to think this is whats goin on.... Not saying it is, it just crossed my mind.
Now, i have read in some forums that business reps have had it in there hand and that it was running WM6. What i think sprint might be doing is getting out to all the places that have RevA, and then move to the non RevA so that this could buy them some time to put WM6 on all of them. They probably figure they will be done buy October. This is why i think some people are getting some dates saying this Monday, and others are getting October or even worse next year.
Im most likely wrong, but it did cross my mind so though i would share it
