Well, I went to one local Sprint store, and left very unhappy. They acted like they couldn't care less about the phone, or me as a customer. Said they don't have them in yet, and suggested I "keep calling to see when we get them, then we can hold one for you while you come in." No willingness to put my name down on a list now, or anything.
I then called another Sprint store (both of these are company-owned, BTW), a bit further away. The initial rep was clueless, but let me speak to the manager. She was also pretty clueless, but at least was helpful. Promised to hold a Photon for me when they actually got one, and that I could pick it up on the 28th (assuming they had the phone by then).
All in all, a fairly poor set of experiences with Sprint, that will be all washed away if I get my new Photon in my hands Thursday.
