[Update: the sale iPad is a third-gen model, not fourth-gen] Starting today, Walmart is launching a sale on several Apple products in the US. The retailer is dropping the price of a 16GB, third-generation Wi-Fi iPad down to $399 -- the same price as the iPad 2 -- and beginning Monday, also bundling in a $30 iTunes card. The third-generation iPad was discontinued when the latest model was introduced in October, just eight months after the third-generation's debut.
