How do I get my ipad3 see my iphone 4s via bluetooth both are next to each other. Both see and pair to my PC
How does this happen?
You have the Personal hotspot enabled with your carrier on the iPhone and iPad?
In order to use your iPhone data over 3G for the iPad, you need to contact your carrier to enable the Personal Hotspot.
You can then share the iPhone data connection using wifi or bluetooth to do this.
