Review: LG Quantum
The Quantum has access to Windows Marketplace for Mobile. The Apps are added to the main menu once downloaded and installed. The Games are added to the XBox 360 Hub. The Marketplace shows screenshots, user reviews, related apps, and how much the app costs to download.
Because the Quantum is made by LG, it has access to the LG Hub. The LG Hub is sort of like a mini Marketplace for the Quantum. There are a number of apps in there that were developed by LG that specifically work with the Quantum, such as Look n Type (texting-while-walking utility), Tool Box(flash light, compass, etc.), and Panorama Shot (camera utility).
There is also an AT&T Hub, which is populated mostly by AT&T-branded services that are already installed on the Quantum.
