hi, i ordered two i phone 6 from the apple online store in the us. my dad is in the us right now and he started his phone for a minute without removing the pre-installed t-mobile sim card. he turned it off right away and he wants to start it finally here in germany with his sim-card. is it possible that the phone did a netlock on t-mobile because he started it without removing the sim? or should we be allright?
