I just found out (yeah, maybe not new for everyone here^^) that i can copy apps that i just bought with my rooted Desire on my sdcard, deinstall the app, get a refund and install the app with my copied apk again.

Now i'm a little bit confused because the app is showing in my market download page. I see it as an "installed" app, i can comment it and deinstall it.
Cracked apps or paid apps that i'm download and install from mobilism e.g. are not showen in my market download site...

My question ist now why and can google or the app developer spot this/me???

Because you're magic, congratulations

Yeah, and you're so intellectual. I can't belive it.

Haha ok?
