Still trying to decide between Wifi and 3G models. (Got 16 GB Wifi on day one) I don't see much of 3G use on iPad, but I'm thinking "just in case" as probably many of us are. For example, I might need to download a file and edit, then upload/email when I'm on the road. Now, are there apps that I can install on both iPhone and iPad, transfer files via bluetooth (not Wifi)? I think that will cover most of my potencial 3G needs on iPad.
