Given the simple nature of the patent, the probable answer is not really. The Patent was originally describing pagers, and shared data (wirelessly) between two pagers owned by the same person, so that appointments, contacts, etc would be shared from one device to another via wireless connectivity. The patent should never have been given, but if its accepted as a valid patent, I'm not sure its even possible to do what iCloud is supposed to do and not violate it unless you make them wired connection only. Every android phone and every blackberry for instance is "using" the patent as described as likely does the Windows phones. Any phone that pulls/shares its content with an email account on another computer is likely in violation of the patent.

It a lot better than some of the crap patents Apple has tried to sue with. Apple problem they are running into is they are getting into the wireless/cloud bussiness where companies like Motoralla have always been and were the leaders in setting it up. The patent looking threw it looks pretty detailed and Apple could more than likely work around it. It looks like it updates indexes to say something changed. Makes it much more efficient in updating stuff. No need to scan the file unless an index saying (look I changed) is updated
Lets see slide to unlock, Pinch to zoom are two great examples of crap patents from Apple.
