Here's a possible way to get WA on the n900. Get another cheap android phone and connect to WA. On the browser of the N900, go to WA page for using WA on another pc. Scan the bar code there with your WA enabled phone. As long as the WA enabled phone is connected to the internet, one should be able to use WA on the webpage through the browser on the N900. Worth a shot in resuscitating the n900.
