Storage deleted on Android devices

[e...@funtomic.com]

Hey all,
We're using Flambe's System.storage for the game's data storage.
I've noticed that sometime, on Android, the local storage gets deleted (using SharedObject).
After doing some digging I found out that it is not such a good idea to keep persistent data on SharedObject.

1) Is using SharedObject is safe for saving persistent data?
2) If not, what else is recommended when I'm using Flambe?
3) I also saw this "solution" or failsafe: http://stackoverflow.com/questions/16737843/adobe-air-sharedobject-android-ios-on-update-not-found
3.1) Is this not recommended for any reason
3.2) How do I save/retrieve a file with flambe?

Thanks,
Eli
