Please correct me if I'm wrong, but can't you just
swap the sim card from your iPhone into the iPad and use that for 3g if you really need it for some reason?
If this is true, then I will be ordering a 32gb 3g model. Otherwise I'll take the 32gb wifi. I doubt I'll need it a whole lot, but it's nice to know that it's an option, especially on vacation when not receiving a lot of calls.
Also, can anyone really confirm that the 3g model has true GPS? This is what Apple's tech specs for the iPad say:
Location
* Wi-Fi
* Digital compass
* Assisted GPS (Wi-Fi + 3G model)
* Cellular (Wi-Fi + 3G model)
So Assisted GPS would be the real GPS which locks on faster, like the iPhone 3g and 3GS, and not the triangulation that the first iPhone had? Knowing this will also help me to decide, thanks. $130 more is quite a bit to think about when one already has an iPhone 3GS.
