The Sony Ericsson Xperia Arc has recently passed FCC with AT&T bands but, as far as FCC filings are concerned, this doesn’t always necessarily mean that one particular smartphone that has been cleared will actually get to that specific operator.
According to a User Agent Profil (UAProf) listing, there’s a certain LT15at model from manufacturer Sony Ericsson Mobile Communications. The original Xperia Arc is just LT15a so the addition of “at” at the end of the LT15 codename could indicate an AT&T destination. The bands are definitely there according to FCC.
The smartphone sports a 1GHz Qualcomm Snapdragon processor, 512MB RAM, 4.2-inch 480×854 FWVGA display and a superb eight-megapixel camera with LED flash with the mobile Exmor R backlit image sensor that enables for great image quality capturing.
