iPhone 3.0 beta 4 installed
Took me some effort but i finally updated my iPhone to 3.0 beta 4. For some reason, i was not able to update using the iTunes 8.2 Pre-release on Windows XP. I kept getting the 3014 error. According to some, the 3014 is generated when iTunes does not recognize the iPhone to be updated as a registered device. Registering my iPhone as a test device did not help. When i got home, i had absolutely no problem updating my iPhone to 3.0 beta 4 on my Mac.

It’s something to do with your network or your ISP’s network, i.e. something in between you and Apple’s servers stuffing up communications. You can use this solution to get around the problem for doing it on your Mac: http://blog.mcchouse.com/2009/08/iphone-os-301-update-error-3014.html
