Nokia has announced the release dates for the Lumia 710 and 800 in Vietnam. Both handsets will go on sale and will be available on April 9th, for 6,299,000 VND and 10,599,000 VND respectively. Nokia Vietnam has listed 21 retailers to stock and ship the two Windows Phones, and all stores will be decorated in Lumia promotion material.
Unfortunately, the Vietnamese keyboard and language aren't supported by the platform, but are on the horizon (as well as Local Scout, Maps, etc.). Nokia has attempted to soften this blow by releasing Viet Keyboard, an app which provides a convenient text input solution for the Vietnamese language.
Users are able to type as they would normally in the app and then copy the text to the clipboard, which can then be subsequently pasted elsewhere on the smartphone. Viet Keyboard will be especially useful for common tasks such as SMS, email social network posting, and web browsing.
