Although being a Mac user since 1984, I am new to the whole iPod/iPhone thing. I just got the iPhone 3G and set it up with my home computer (MacPro 8 core 2.8GHz). Everything seems to work great. The problem is that when I brought it to work and hooked it up to my work computer (MacPro quad 2.66GHz) It tells me that I can't add an application from iTunes without erasing all the apps I already installed at home. I am logged into the iTunes store with the same account at both places so the Fairplay DRM should be identical. I tried setting it to not sync and just manually drag the App to the phone but it won't work... is there any way to do what I want? What if I had multiple computers at home? Would I always have to sync the iPhone from the same computer every time? Since I'm authenticated using the same credentials I don't see how this could be a "legal" requirement especially considering that one purchase can be synced to an unlimited number of iPods/iPhones and I only have one mobile device!
I did do a search and found a bunch of stuff about using disk mode, but that only applies to iPod, not iPhone!
