If you have encountered issues syncing your iPhone with iTunes on your new Windows 7 PC than you might be in luck. If you run an Intel P55 motherboard from Gigabyte you can now upgrade your motherboard Bios with a beta version that is supposed to fix the Apple iPhone Sync issue.
As Gigabyte was able to fix the issue with a Bios update it would imply that the problem is not a Windows 7 problem. Microsoft and Apple are supposed to also still investigate the issue.
Gigabyte published the beta Bios for GA-P55-UD4P (rev. 1.0) here for download. Via Heise.
