BE WARNED! Amazon disabled my current SIM card (in my old phone) without warning when the new phone shipped. This meant that I was without a cellphone for the duration of the delivery. It was only a few days, but as the cellphone is my only phone, and I was expecting international visitors, it was a huge disruption. It is not possible for Cingular to reverse a SIM disabling, so despite a lot of complaining I was not able to get a phone during this period.Amazon's help staff were also completely useless -- I couldn't get their "we'll call you back" phone support service to work, and the email support staff I reached weren't able to understand the problem.The product has worked fine since; but I doubt I'll be buying phones through Amazon again.
