Is there a way to tether my iphone to a wireless router? Specifically, using an Apple Airport Extreme. Moving to a rural area - cell coverage is good and I have unlimited data; however I need to be able to get data to my TV's etc. Until I can get coverage by a provider, is there a way to share my connection with multiple devices easily? I do not use a PC, use an iMac - so i can't do the "network share" trick that Windows PC's allow. Yes, i'm aware that even though I have unlimited data, my cell provider may not be happy with my plan and/or may be against TOS. Simply asking theoretically.
