People, get your build numbers right if you are gonna talk about this stuff!
There is no 405, 409, or whatever.... It is
425,
429,
604,
632... The confusing with all these leakes versions is already big enough...
Furthermore, everybody is talking about .429, but I yet have to see the first real file. Even on
http://messenger.msn.com/beta there is no 429 (like mess.be reports) It still is 425...
Also, yes it might be crazy for MS to release a public build lower then an exitsing leaked beta. But remember that you aren't even suppose to use, heck know, builds >604 (unless you're a beta tester)... So don't go with all this bashing at MS, this is a normal way of development and it is the leakers you should be bashing...
