No problem with my phone either before or after new releases.
BTW, it's hard to use s few complaints on this one forum as an indication that the OTA release is buggy/flawed. It's a very skewed data set.
For every person who has an issue and bothers to go online to find other people with the very same phone to complain about it, I'm willing to bet there are 100-1K users who have bought these phones from VZW and haven't had any issues with the firmware update.
PS. I'd do a hard reset on your phone and if the phone continues to crash, take it in. You can then just tell them you "tried that already" since this will probably be their first way to turn you away.
