I’m a digital (as well as physical) packrat. I have all my emails going back to 1994, most of the documents I’ve created in that time (as many as allowed by my previous employers) and a whole collection of IMs. The text messaging on my phone has always been a missing bit of data - until now there’s been no good way to get it off of my phone.
As details have emerged on the iPhone’s internal data structures, I realized that there might be a chance to extract those text messages and archive them offline. Also looks like voicemails can be archived in a similar fashion. I’m almost ready to share the utility with the world, but until then I thought I’d share my iPhone database structure notes. For those geeks interested in such matters, click through to the extended entry. (Thanks to Erica Sadun for porting sqlite3 to the iPhone - made this whole thing much easier)

iPhone模拟器文件目录
在编程时，大家肯定要知道应用程序在哪个目录下，iphone也不例外，也有个工作目录，开始时让我也让我找了老半天。下面工作目录的路径：
/Users/stephen/Library/Application Support/iPhone Simulator/User/Applications/
