Hi, I have been using iPhone 4 form a while now and use Apple iTunes to synch the iPhone with my Dell laptop. I am unable to find out why iTunes is giving so many problems. Everytime I connect my iPhone to my laptop, iTunes ask me to sync all the apps which are installed in my iPhone. And if I try to cancel that prompt, I am getting a warning;”Are you sure you do not want to sync the application? All the existing applications and their data on the iPhone will be removed/deleted.”What must be the reason behind this problem? Does anyone have got a solution for this? Please help me.
