Is there any way to mirror from iPhone to iPad? I want to use some navigation apps installed on my iPhone that require a 3G connection, but want to use an iPad for the display mounted in my CMV. (Commercial motor vehicle). I'm trying to avoid having to buy an additional data plan for my iPad. I have an unlimited data plan on my iPhone. I don't know anything about tethering.
Do you have tethering on your data plan? If so you should be able to install a nav app on your ipad and use your iPhone to setup a personal hot spot ( tether). This will give you the data access the nav app requires. Below is a quick link on setting up a hot spot. http://ipod.about.com/od/iphonehowtos/ss/Use-Iphone-Personal-Hotspot.htm
