Unable to Update Apple TV's Software Beyond Version 5.1

I successfully updated my Apple TV to versions 5.2 using the following instructions from Apple's website...

If you have a micro USB cable (sold separately), you can restore your Apple TV from iTunes:

1. Disconnect the power and HDMI cables from Apple TV.
2. Open iTunes and verify that you are using the latest version: iTunes > Check Updates
3. Connect one end of a micro USB cable to the back of your Apple TV, and the other end to one of your computer's USB ports.
4. Apple TV (3rd generation) only: Reconnect the power cable to your Apple TV.
5. Select your Apple TV in the Source list, and then click Restore.

Your Apple TV will restore to its factory settings, and will also download and install the latest Apple TV software update. This process may take some time. Do not disconnect any cables from the Apple TV until the restore process is completed.

Details:
Apple TV version: 3rd Generation
Model number: MD199LL/A
Software Version: 5.1

Manually Transferring a Numbers Spreadsheet from an iPad to a Mac

Problem: You want to manually transfer a Numbers spreadsheet from your iPad to your Mac.

2. Tap “Send to iTunes,” and then tap the document format you want to export to: Numbers, PDF, or Excel.

Extending iPhone's Battery

Problem: Your iPhone's battery doesn't last a full day without recharging.

Solution: From Apple's website...

Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness & Wallpaper and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness & Wallpaper and set Auto-Brightness to On.

Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.

Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.

Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and disable notifications for select applications. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.

Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > Privacy > Location Services or use location services only when needed.

Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
