From the article:
Dell today formally entered the smartphone race by launching the Mini 3. The full-touchscreen phone depends on a customized version of Android and will have different features based on the region. While most details aren't available, the China Mobile version will be limited to EDGE data but use the government-supported OPhone interface and app store. Other countries should get localized 3G and should also have Wi-Fi as well.
