#1 intrigues me. So rather than paying Verizon an extra $30+ a month for tethering, if I JB our 1st gen IPads, we can tether for free when we get an IPhone?
Short answer- Yes!
MyWi OnDemand will set you back a one time fee of $25. Then, as long as your iPhone and iPad are jailbroken, have MyWi installed and bluetooth enabled on both devices, it's all automatic... Say you are in a car and you wanted to check something on the internet on your wifi-only iPad... Just turn it on! It will detect there is no wifi service and then automatically connect to your iPhone via bluetooth in order to use it's 3G service. Then when you turn the iPad off, it disconnects from the iPhone, thereby saving battery life while "sleeping". It really does work well.
Pretty expensive for a Cydia app, but it's well worth it in my opinion! It's fully compatible with 4.3.2 as well....
