My dog got hold of my Droid X, so I replaced it with a Razr, which won out over the iPhone 4s becase of 4G and screen size. First day, I found that my connection, whether 4G, 3G, roaming, whatever, would spontaneously drop out. No rhyme or reason behind it. Verizon tech support tried to be helpful, but the tech sounded like she was grabbing at straws. She's sending me a SIM card.
However, yesterday evening I went to Motorola's website and downloaded the latest software update, 6.11.748.XT912. This update is supposed to provide:
IF YOU HAVE NOT INSTALLED THIS UPDATE, DO IT NOW! My Razr is now working flawlessly, and (aside from battery life) I can say I love it. The Razr now has the highest sensitivity of any phone I've owned, and that's a lot. I've been with Verizon a LONG time, beginning when it was Metro Mobile CTS. I live in the country, 60 miles south of any major city, and I can now travel between the two without losing a signal!
The RAZR ROCKS! (except for the battery life, like I said, but that's what car chargers are for )
