Nokia contact with me, and now I have a new one N900 and apologized.

Now the question is...

How prevent this "memory corrupted" again. Never connect it at pc? never disconnect it from pc wihout use "disconnect hardware with security" ? If I connect it to my car radio with usb, no acctivate never the massive storage? I must use microSD or bluethooth to copy files, songs, backup from pc to phone? Is ubuntu the solution?...

Thanks.
