How do I utilize the hotspot from a blackberry bold 8650?
Did you mean Bold 9650, as there is no 8650. I'm sure just a typo. However, none of the Blackberry devices support providing a hotspot for other devices to utilize WiFi such as the HTC Thunderbold or the iPhone 4. Perhaps this will be a feature added in future Blackberry releases.
If you were not referring to hotspot for a device but rather using the WiFi feature to connect you device to a public or private hotspot, then check out the "how-to" video below:
Hope this video helps,
Thank you for the information provided. The BlackBerry Bold 9650 is not Mobile Hotspot capable. This device has the option to tether it to a PC. Click this link to learn more about tethering your device: http://www.verizonwireless.com/mobilehotspot
