I'm living in Germany and recieved an unused iPhone 5 A1429 without SIM or contract as a gift. I'm planning to use it abroad, likely with prepaid SIM cards.
The phone is not activated yet and I am very much afraid of it being locked to the first network or SIM card brand I stick in. Is that what happens during activation? What's the purpuse of activation?
Unfortunately I could not find any useful information from Apple, other than I have to have a SIM card inserted to activate the unit - WiFi won't do.
