Hi this is an alternative android market apk i used to get hacked and cracked paid android apps for free.
I thought it was a great apk to use before i lost my htc desire so i thought id let everyone know about it and get a link
Download Blackmart alpha V0.49.92 here
There is a newer version but when you open this it should say download update and it should work
note you may need to turn on install 3rd party apps in development setting to install this apk
hope this helped enjoy =)
