Would I be able to use a phone with a bad ESN as a dummy phone for modding? I know ones that are good will ask it be activated at the first power on, but will one with a bad ESN ask that or just go straight to HOME?? I travel alot and I really don't need my phone down while I try to fix things that I screw up while having a little fun modding and playing around.... Thanks for any info you can give!
