Help! I am new to the iphone and so far like it a lot. I purchased an iphone 4 last week. I set up to receive my emails on my phone and that works. But the day I set it up, I stopped getting the emails on my PC. Sprint said the settings look fine on my phone and they had never heard of that. I contacted Comcast/xfinity and they were not helpful (Thought a technician will try if I pay a monthly fee). What can I do? Or what did I do wrong? I can still send emails from the pc-but only receive the reply on my phone.
