The Mobilelite Wireless G3 and Pro use a different app than the MLW221 and MLWG2. The New app is called "Mobilelite Wireless". The older app is called "Kingston Mobilelite". Be aware that the new app will not work on the MLW221 and MLWG2. You still need to use the older app for those. But the old app will work on the MLWG3.
