Here are links I found interesting on May 3, 2012:

• iOS: Troubleshooting Personal Hotspot – Useful information about troubleshooting personal hotspot issues on iPhone and new iPad. The most important takeaway: "Note: If you leave the Personal Hotspot screen or put your iOS device to sleep, the device only broadcasts the Wi-Fi network for an additional 90 seconds. If no devices join the Wi-Fi network during that time, iPhone or iPad Wi-Fi + 4G stops broadcasting your Wi-Fi network. You can start broadcasting your Wi-Fi network again by tapping Settings > Personal Hotspot."
• Apple Trademark List – Up-to-date list of Apple trademarks and service marks. Useful when writing about Apple products.
