A moderator probably merged the thread. Although I thought it was standard protocol to leave a message saying they were merged.

And because you cannot access the iPhone's filesystem (at least not without jailbreaking it I think) you can't get to /var/opt/. Though I'm not sure that would even exist (I know OSX is based off of Unix but I'm not sure if the directory structure is the same).

It could be similar to the difference between where Windows and Linux stores its files. C:\Program Files vs /usr/.

Though I would imagine any iTunes backup would save the save data.
