They're the same phone, just rebranded for different carriers. For example the LG Optimus S if for "S"print the LG Optimus U (not "you") is for "U".S. Cellular and LG Optimus V is for "V"irgin Mobile. In my opinion the Optimus is a great phone, and you will be very happy with it.
Yes. I currently own an LG Optimus V and it has a Body Glove Case on it. Any case that is designed for the Optimus S will fit the Optimus V.
LG Optimus M+
Yes, the LG Optimus S is considered a smart phone. The LG Optimus S supports internet connectivity, WiFi, micro USB, email, and HTML among others, and runs on the Android v2.2 operating system.
The best out of these two is the LG Optimus 2x however.. it being an LG phone it has horrible service.
It is not adjustable.
