$170 for something that only works on Android versions "up to 2.2.x" seems like something that has a small and shrinking market these days. It's not clear to me that it does anything more than freeware undeletes do, but I dunno.
Symantec would be happy to sell you something for your Android phone - http://us.norton.com...-mobile-security/
Phones and tablets are more powerful than PCs were just a few years ago. One has to imagine that just about anything that can run on a PC will soon be running on Android (subject to the I/O limitations inherent with the platform).
There's a whole cottage industry of hacking these things, e.g. http://www.droid-lif...xus-7-bootloader/ They're a lot braver than me, and apparently have more free time. ;-)
My $0.02.
Cheers,
Scott.
