I updated my itunes to 10.1 today and it has caused a couple of problems. I can no longer backup (I have disabled the backup feature) or transfer purchases from my iPhone without stalling for hours and hours. Under the apps tab on my iphone, I have sync apps enabled. This is a problem because I usually purchase apps through my iphone, not on itunes. When I try to sync my phone, it deletes recently purchased apps and I am also unable to properly transfer my paid apps to itunes (stalls for hours during transfer or just stops and doesn't transfer anything). I would like to uncheck sync apps, but it just starts deleting all of my apps. P.S. sync new apps is enabled. 10.x seems very buggy on windows 7. I would really prefer to stick with 9, but I need 10 for for ios 4.x. I'm really considering getting a macbook, in hopes that I will not have future problems such as this. Any help will be appreciated.
