Ok, I have been absolutely thrilled with the speed of the device and the n/w until today. I had some driving from East fo Sacramento to North of San Francisco and then into San Francisco. The reception on this trip is fine, when I spoke to people in the area they said that Verizon has the best service. I was even in a building with a Verizon network extender. Despite this, I had problems with signal all day until I got to SF in the afternoon where things are back to normal. Especially data but also voice. Weird stuff like I have a perfect call on the phone, end the call and immediately dial someone else to be told there is no reception (happened 3-4 times). Tried switching the phone off a few times. After an hour of the same problems, I tried to switch between 3G and 4G, tried to switch the data off, tried to switch to roaming mode. Nothing worked. Has anyone seen anything like this or have any suggestions. Hope it was a one off because if it's a regular occurance, I will need to return the phone and I love the thing so far.
