FIX: calendar probs "sync server failed to sync the iphone"

Question

Hi all,
Out of nowhere my 3GS with OS4 stopped syncing via iTunes. (I use USB and PC with XP). Error message included "sync server failed to sync the iphone"
One to try.......
Go to My Computer
C:\Documents and Settings\user name\Application Data\Apple Computer\Logs
There are file with names like
asl.987429_25Aug10 (for example)
I opened a file with the date when the problem occurred.
Scroll down and look for a line like this.
USB mux port 32498 for device 9: No such device or address
[5968 @ Thu Aug 26 14:06:51 2010] [(unknown facility) iTunes.exe] MobileDeviceConnectlocked (thread 592): Could not connect to lockdown port on device 3e59d5e8fc22f5cad8a409af80aedd59396ee165.
Take note of this number 3e59d5e8fc22f5cad8a409af80aedd59396ee165 (or just the last few digits). Then..........
Go to My Computer
C:\Documents and Settings\User name\Application Data\Apple Computer\SyncServices\Local\Copy clientdata\
I had 3 folders, all with long alphanumeric names, lets call them A, B and C. Open each of them in turn; they will have a the text document "clientname". You should fine something like this:
"com.apple.MobileSync.3e59d5e8fc22f5cad8a409af80aedd59396ee165" where the alphanumeric is the same as the error message. For me this was in folder A.
Now, go back to the \clientdata folder and copy the Folder (folder A - with the correct "clientname" file in it) to your desktop (so you can restore if it doesn't work)
then delete that folder (folder A) from the \clientdata folder.
Close all and reattempt to sync whilst turning around 3 time anti clockwise with your hands on your head.
Worked for me - no loss of data.
Good luck!!!!
Cheers

This just worked for me, thank you! It's a little confusing at one point -- the folder you're looking for is called clientdata (you have it as "Copy clientdata" at one point), and the folder may have other items in it, which will also have long names, but you need to ignore those items and open the file called clientname -- INSIDE THAT FILE in one of the folders, you'll find the long name you're looking for. THAT'S the folder you want to remove.
