Jailbreak: Need Top Option + Restore + Choose ipsw Anymore? Before a device was to be jailbreaked, all the tutorials recommended connecting said device to iTunes and then clicking option + Restore &gt; Choose ipsw.

Recent tutorials don't include these steps any more. Rather they just mention restoring through iTunes and not over wifi.

Is the option + Restore &gt; Choose ipsw Necessary Still For Jailbreaking?
The basic restore through iTunes will download the latest software image and restore it. This is equivalent to downloading the latest ipsw and using the Option + Restore method. 

The Option + restore method has typically been useful for situations where you need to restore to an older or modified ipsw file, which was more useful in the earlier days of jailbreaking.
