I'm using a Verizon Wireless iPhone 4S. I am unable to get push notices for my Twitter account. I've tried Twitter, Twitterrific, Boxcar, and now Notifo and still no notices when there is a new post to any of the people I follow. I've asked Apple and no response. I asked Verizon and they say not on their end. Twitter and Boxcar do not response to request for help. I had no problem with an Android cell phone, but I just can't get push notices with this Verizon Wireless iPhone. Any ideas?
