Maybe it really is something related to their network, and not the phone then? Anyone other than the south with this problem?
I'm having the same problem with the 2 iPhone 5's I purchased Friday. Both of the phones are on Verizon and are the 32 gb versions and I live in San Antonio. I tested the Verizon i5 demos and they all had the same delay I am experiencing, maybe a software glitch? I'm going to the Apple store today to see if anything can be done.
And I don't think the iPad would share the same problems because I thought they had different LTE chips installed. Also, wouldn't Sprint customers have the same problems we are?
