Question: I just uploaded my application in the market, but I'm not able to purchase it (it's a pay app).

I saw [here](http://market.android.com/support/bin/answer.py?hl=en&answer=141659) that it seems to be *made by design*, but then why the error message is `Server Error try again` ?

Is there a way to bypass that ?

Answer: 
Do you have an Android Developer Phone? If so, you can't purchase your own app by design. Since ADPs are unlocked, there's nothing preventing an ADP from easily pirating any app it downloads, so they are purposely cut off from downloading paid apps.
Yeah, I ran into the same problem. I uninstalled the APK from my phone so that I could download it from the market. It works fine for my free apps but not my paid apps. I guess there is no need for QA and the customer to use the same process lol
