So I've been an iPhone user since the 3G launched and I'm a little perplexed by something I've noticed over the past few days. Since switching to Verizon earlier this week--I've noticed that when I'm a call and receive an another call--if I end the first call--it hangs up on both of them instead of switching to the incoming call waiting. In the past--when I'd hang up on the first call--the new one would be answered seamlessly. Is this a limitation of the Verizon network or a software bug? Any insights? Pretty frustrating.
