I will be in Germany for a couple of weeks and I am planning on taking my iPad as my only computer. My question is will I be able to insert a Vodafone 3G sim card and use it straight away, or will I need to connect it to iTunes to activate it? If anyone could point me in the direction of an Apple support page or whatever that would be appreciated. My plan is to leave my Mac at home, so if I will need to connect it to iTunes after inserting the sim card, it will be useless to me. My iPad is a first generation 3G (factory unlocked) currently on O2 UK. Thanks!
