So i talked to sprint...

I talked to Verizon once. For no reason really. Just called them up one time and pretended I was a Verizon customer angry about something on my Pre Plus. Pretty funny actually.
 
The sprint store in St. Louis told me it was strictly first come first serve. they weren't taking reservations or pre-orders or anything....good luck.
 
Yeah, I'd definitely show up b/c no way they are going to turn away someone with money right then and there. Oh and I'm sure they'll have plenty! The sprint store I'm getting my wife's EVO from said they are going the 1st come 1st serve route so I'll be there bright and early about 6:45ish!!
 
Oh, by the way, I got my evo monday with a free screen protector set and gel case.

I love this phone :)
