I got my nexus from Google play store today, I put my At&t Sim card in it and what horrible signal this phone has, both data and cell. In the same location my nexus goes from no cell signal up to one bar, put the Sim back in my Sony Xperia Neo V, 4-5 bars. Data on nexus= constantly switching from 3g to H mostly 3g even seen 2 on there several times, data on my Sony constant H. I tried changing APN to several I found on line, none made a difference, speedtest on the nexus = 578k down, 131 up. (average after 5 tests) speedtest on my Sony = 1741 k down, 988 k up. I don't think I'm going to be live with the nexus, no cell service at all in my home zero bars, nothing, 2-3 bars on the Sony. What gets me is the Sony Neo is just their mid range phone. Going to see what the Play Store return policy is, or maybe try an exchange, or just return it, or sell it on ebay anf buy an Xperia S.
