This is the case scenario:
I normally synchronize with my desktop computer moving items from my iphone to the computer using itunes.
Now, I had to synchronize with my laptop which has an old database. I had installed new applications on the iphone since then. It happenned that the laptop took control and erased my new applications. Is there a way to prevent this or to tell itunes to erase its library and fully take what it is on my iphone?
