I can help fix your phone. The advice u got from the VZW rep is mostly not true. I have been a LG fan for awhile (about 11 years), until some of their recent pathetic models (Choc.1, vx8600, etc.), which I did owned, and very disappointed. I switched to Samsung and feeling fine again.
The U550 and VX-8700 are very similar in design and features....u can compare them here.... http://www.phonescoop.com/phones/compare.php?id%5B%5D=1104&id%5B%5D=1414&id%5B%5D=&id%5B%5D=&id%5B%5D
The Samsung will outperform LG....
