A while ago, I had a problem where my iPhone 3G 8GB would take ages to sync with iTunes, particularly when it got to the "backup up" stage. I somehow fixed this, but I can't remember how.
Recently, iTunes upgraded itself to version 22.214.171.124, and now my slow backup problem is back!
Can anybody tell me how to speed up the backup process?
I don't want to turn it off, but it used to do it so much quicker. It currently takes at least 5 minutes to backup, even though absolutely nothing has changed on iPhone or PC. I also don't want to have to reset my iPhone and install everything again.
My computer is a PC running Windows Vista Home Premium 32-bit.
