There is semi-official confirmation from Nokia India on Twitter that least that the Nokia Drive app (that's the full voice navigation program) will be made available for non-Nokia phones--but for an undisclosed price. Nokia Drive, up till this point, was thought to be an exclusive app for Nokia Windows Phones. But perhaps Nokia is either reconsidering this approach or this was always the plan and we're just hearing of it now.
The info comes by way of a Tweet stating that Drive would be free for Nokia users and paid for non-Lumia phones. This tweet was then reTweeted by Nokia India, which is the usual way of showing agreement on the Twitter. About an hour later, Nokia India again re-Tweeted a similar message but this time about Nokia Maps--the Bing alternative app used for finding places near your location and some basic directions.
For Drive, we think this makes 100% sense for Nokia. After all, their app was just pirated a few days ago, so what better way to stem piracy than to offer it for a modest price to everyone? Nokia Maps, on the other hand, seems a bit odd to charge for as it seems like something they should give away. However, we have no idea on prices for either, so perhaps they're looking to keep it on the low-end of the pricing scale? Either way, while all of this seems legit, we'd still like to see a little more confirmation that this is indeed the plan for Nokia.
Update x2: We've just had word from ZOMGitsCj, and it appears there was a misunderstanding. Nokia Drive will not be making its way to other handsets via the Marketplace, it will be Lumia handsets only. Nokia Maps on the other hand will be made available for everyone.
