My first tip:
When you receive your Fire perform the following steps first:
1. Connect to your WiFi.
2. Register your unit with Amazon if it is not already registered with them.
3. Charge your unit for four hours.
4. Check under settings if you have firmware version 6.0.0 or 6.1.0. If you have the former version, go here to update to the latter version:
5. Have fun !
