I made a few backups with my Nexus and would like to transfer them over to my computer. Anyone know where they're located in the data directory?

I downloaded the Nexus 7 toolkit but I get it to work. Any one have better directions? What's the best way to backup?

Anyone know how to get WhatsApp working on the Nexus 7? I can't seem to get it working on a tablet.

There's a USB port on the Nexus 7, is there a way I can connect my device to a USB external hard drive? I know you can do it some how.

I thought upgrading would make my Nexus 7 better but it seems a bit sluggish than before I upgraded. Can I downgrade back to the old version?

Any ideas how to do that guys?
