I bought my iphone on August 1. I was so excited to get it. I decided that I wanted a new number to match the area code of the new state I was living in. I sent out a text message to my friends telling them about my new number. About a week later I was noticing that I wasnt getting many text messages. I just assumed that some people hadnt updated their phones with my new number. Then another week went by and I was starting to get phone calls from my friends asking why I hadnt responded to their text messages. I was finally able to deduce through certain tests that I was not receiving ANY text messages from other carriers. I contacted AT&T and they told me to make sure my software was upto date, which it is. and to power cycle the phone at least every 12 hours for 4 days, which I did. It still hasnt corrected the problem. AT&T says that its not their fault, but rather the fault of ALL the other carriers. They dont really offer much assistance. Any advice??
