Best AllFiles hack for S60 3rd Ed FP2?

[NewOwner]

I have a need to access to the C:\Private folder on my T-Mobile E73. I've never hacked a Symbian phone before, and at first thought HelloOX (http://www.nokiasymbianthemes.com/explore/the-ultimate-symbian-hacking-guide-tools-issues-software-firmware) seemed like a good solution. But it apparently doesn't provide AllFiles support. Does anybody have a suggestion for a good hack? I prefer something that can be cleanly removed when I'm finished. Thanks!
