Care to elaborate in your own words why you think so?
I will be quite peeved if something I have been doing for years with combinations of tools like Dropbox and Truecrypt becomes more difficult or costly to me or my customers due to a patent like this one.
Basically, it comes down to: the claims in patents are interpreted very narrowly.
If your device/method doesn't exactly match the claim elements of the independent claim(s) in Apple's patent - even one little difference in implementation is enough - then your device/method is not infringing. Don't worry, be happy.
