In the meanwhile, Apple has also asked the users on the support forum for submitting the make of their computers, the version of their BIOS, the model of their iPhone or iPod, and also some other information in order to help in troubleshooting.

An Intel spokesman has said on Tuesday that their leading theory is BIOS or the system configuration issue, but they are still in the process of investigation. He said so while referring to the reports on the support forum of Apple that the users have not been able to get their iPhones synchronized after they have upgraded their operating systems to Windows 7, and particularly the 64-bit edition of the latest operating system of Microsoft.

The users have first reported the iPhone sync problems with the Windows-based PCs in the middle of September, but the traffic on thread was dedicated to the issue which was picked up when Microsoft released its Windows 7 on Oct. 22. Mr. Bahr has said in a kick-off message that he could plug in his iPhone again and the iTunes will recognize it too, but will say that iTunes can not connect to this iPhone due to an unknown error that occurred (0xE8000065).
