If you are like me and want the ability to return to a previous version of the iPhone OS then you’ll need to start taking back-ups of the downloaded OS images.
When you click to Update your iPhone in iTunes and select Download with the intention to install later, you’ll be able to take a copy of the downloaded file before you install.
Once downloaded, this can be located under your User folder /Library/iTunes/iPhone Software Updates

Having recently convinced my wife that she needed to make the switch to Mac OS X I was horrified to find that the Mac would not open WMF files. Over the years I have accumulated a large collection of clip art files in the WMF (Windows Metafile) file format and didn’t really want to start again.
I found the quickest way to resolve this was to convert all of my existing WMF file into the PICT file format. Using one of my Linux servers I ran the following shell command against my picture library:
find /home/user/clipart/ *.WMF -print0 | while IFS= read -rd $'\0' f;
do echo "[$f]";
convert "$f" "$f.pict";
rm -f "$f";
done
This creates a list of files who’s file-name ends with WMF. We then loop through each of these file-names converting each and saving it with a .pict file extension. The IFS= read -rd parameters are absolutely necessary should your WMF files contain spaces.
