I got very lucky, there was one store near me that got a shipment of them in yesterday. I picked it up but hadn't opened the package or activated it yet, because I hadn't gotten my screen protector in the mail and I wasn't about to use it without having that covered first.
My cousin had bought one with me yesterday too and had already gotten a screen protector. I looked around on the menus on her phone and specs and everything. I had a Prevail before that I bought on ebay, had it glitch and sent it to Samsung, and then sold it on Craigslist when I got it back for what I bought it for. Made me skeptical about getting this new one right at launch. But eh, what the hell...
I finally opened the package today because the screen protector came, but I'm giving it some time to charge before I activate it. I'll list everything that I think people would want to know about it. The screen is 3.5 inches, feels sturdier than the Prevail just because it weighs more. Just powering it on, the little jingle it plays when the Boost logo shows is different. It also starts up saying "Welcome to Boost mobile" and says we will now activate your device, which I've cancelled. Same 5 home screens like the Prevail. It has that Boost ID thing in the launcher at the bottom instead of the browser like the Prevail had.
Specs.. I'm listing everything I see just to cover all bases..

Listed under Internal phone storage, it says Available space 0.93 GB. I have not downloaded or added anything to the phone, when I go to Manage Applications, for Internal storage, it has 59MB used and 0.93 GB free, again.
I like the texture on the back of the phone. The SD card is only accessible after removing the battery cover, which comes off just as easily as the Prevail did. I like that there's not a little SD card cover thing. Just a nice touch.
Those are just a few things I noticed so far, comparisons to the Prevail. If this info is listed somewhere else already, sorry for reposting old news. I just had seen specs were asked about and shared what I could see.
If I missed anything, let me know.
