BEWARE OF BUYING THIS PHONE FROM AMAZON WITH CINGULAR.I tried buying this phone from amazon.com with amazon.com as the seller. I finished the checkout process and then in 5 mins, I got an email from amazon.com saying, "Your order has been cancelled because cingular needed some additional information, which we cannot provide." A ridiculous reason, to put it mildly. Couldn't they have asked me for that information? I later tried for a customer service phone #, but couldn't find one. All I found was an email address and I emailed them and got a reply (after 2 days) saying that they cannot do anything!!!Later I bought another Cingular phone at Letstalk.com and during the checkout process, they asked me a lot of questions ("additional information" according to Amazon.com) and I got the phone without any hassles. I even ported my old phone number.Such a ridiculous service could be expected of Amazon.com only. I don't understand why they sell cellphones when they don't know how to do it!!!If anyone wants to contact me, send me an email at rphanikanth@yahoo.com
