And, just as I suspected - DL30 is not a RC, just another test build from more than a month ago.
I'm very glad of this. While DL30 isn't bad (hell, it's FroYo!) it ain't "all that AND and bag of chips" - still very much a work in progress IMO. As Adryn noted, it's not even cleaned up internally and has a bunch of typo's and leftover Epic 4G frameworks and other garbage trails in the code.
EB01 - Would be Feb 1, 2011. I'm willing to wager that's probably the 2nd build since DL30. I imagine there would have been an EA15 or so that would have been the 2 weeks "return of the bugfix" from DL30, and EB01 is now at least the 3rd Gen FroYo test build.
It's kind of sad, I get the impression that if the SF didn't have so many stupid rushed-to-market software glitches (which are taking VZW's testers to try and fix with DJ05, DL09, and now the new "fix" for the fixes) we would have had FroYo months ago with everyone else. Instead, the VZW team assigned to the SF has to spend months troubleshooting what Sammy should have tested and QA'd the first time around, before the thing was even released.
Don't get too attached to DL30 peeps!
It won't be here for long. It's really more of a functional proof of concept than anything else.
