I just called one of the independent Sprint retailers on the locator list. The lady I spoke to said that they wouldn't have any on June 6th but that you could come in and order one and they would have it on Monday. She also said to check back Thursday and Friday and if it's in their system they can order it then for you. That's my back up plan. I really want to get one Saturday (planning on getting to the store at midnight) but since every store I talked to said they are getting tons of calls each day, I'm trying hard not to get my hopes up too much.
