Apple’s new iPhone 3G may have made the biggest splash in the smartphone pond on Monday, but it wasn’t the only splash. Earlier in the day, Samsung Electronics debuted its Omnia, a device seen as an iPhone contender. Samsung’s Omnia features the Windows Mobile 6.1 Professional operating system, a wide 3.2-inch WQVGA LCD screen, a five-megapixel CMOS camera and a high-resolution touchscreen interface. Internal memory options are 8 GB or 16 GB, with an extendable slot for additions, and a GPS receiver offers navigation and geo-tagging capabilities.
