While gMaps Pro vanished from the Marketplace a few weeks ago, it's back but with a slight snag. After dealing with copyright issues and re-branding/updating things, the app was restored to the Windows Phone Marketplace as a new submission. This basically means that if you had previously purchased gMaps Pro, you won't be eligible for any future updates without re-purchasing the app.
To ease the pain of the situation and to celebrate the Marketplace reaching 100,000 apps Alexey Strakh, gMaps Pro's developer, will be offering gMaps Pro (regularly $1.99) as a free app for tomorrow (Friday, June 8th) only.
We have to tip our hat to Alexey for trying to make the best of a not-so-good situation. For those who purchased gMaps Pro before it was removed, nows your chance to get the current version. This will enable you to stay current with all the updates as they become available without the need to re-purchase the app. Everyone else... you get a heck of a deal on a nice mapping app.
You can find gMaps Pro here at the Windows Phone Marketplace. We aren't sure when the pricing change will kick in so if you don't see it right away on Friday, check back later.
