Currently have two 4S's with Sprint. Our contract ends today and we are going to switch to Verizon. (Sprint's coverage and data appears to have actually gotten worse here) If I order phones from Apple (and assuming they get here before the beginning of November), will I be able to port our numbers to Verizon if we wait to activate until the end of the month? Or will they activate right when we receive them? We would likely stay on the 4S's until the end of the month so we aren't double paying for mobile plans this month. Thanks!
