I am migrating from a WiFi-only iPad 1 to an iPad 2. I am considering getting a 3G capable version for the few times I am not in WiFi and for the GPS capability. I only intend to activate the 3G service a few months of the year; mostly when I travel to avoid the high daily WiFi fees at the hotel. Will I be continuously nagged by the iPad to activate the service? If it does nag, is there a way to turn it off?
