iPhone What SQLitedb (or other) file to edit

Selling iPhone JB/UL

I used an SQLitedb editor to delete address book entries.

Disk Aid allows for my created files deletion.

Only potential glitch I see the Apple Store app.

Am thinking even though I logged out there might be ID info stored in
private>var>mobile>Library>com.apple.itunesstored>*.SQLitedb

but would need instructions of what table(s) to edit.

Any comments appreciated!
