How to download a large, compressed file to the iphone
<p>I want to download a 90MB sqlite file to my iphone app from the web. So I'll need to save the data to disk as it comes in to avoid having too much in memory. This is similar to this question -

<p>But I'd like to zip the file if possible. How can I handle unzipping such a large file? It's about 20 MB zipped.</p>
