Something like rsync with the iPhone-sdk
<p>I'm looking for an efficient means of copying an online file to the local iPhone. Something like RSync would be an ideal technology to use, since it only transfers the bytes that are different; does anyone have experience with anything that fits my description?</p>

<p>What I'm specifically trying to accomplish is the transfer of an SQLite database hosted via http to the iPhone. I expect the database to grow in time; hence my search for an efficient means of transferring the data to the iPhone.</p>
