The SIM Card error I have read about it is a real deal breaker for me when it comes to this phone. The hardware is beautiful and with Sense 5 on the horizon, the software is top notch. However, my GNex currently also has a problem with the SIM card that requires me to pull the battery, pop out the SIM card, pop it back in, and reset the phone. It happens many times daily and I am really looking forward to getting rid of this issue. However, if the DNA is still suffering from it, then it looks like I might need to continue my search elsewhere.
