so i was in my sprint store in st. louis to activate an old phone today (killed my pre for good when i dropped it on its face and broke the screen) and the tech said the stores will open at 8a.m. on june 4th. he also said that there are some 4g towers up and running in st. louis so there will be limited 4g availability on launch day. he didn't know where and said they couldn't get a signal at their store but said there are some towers up and they are currently getting more up and running. i hope i can get coverage!!!
