I enjoyed the gravity trial so much that I decided to purchase it from the OVI store. However, its an older version than the trial and for some reason both copies are now on my phone. I dont seem to be able to access the beta versions on the paid for app.
Why would the paid for app be worse than the free trial?
To answer my own question,
I deleted both versions, and downloaded manually from the Gravity website.
As I had the licence from the OVI download, the install worked fine and allowed me to access the betas.
i just follow the developer on twitter and each day he posts a link to the newest alpha version, which i download and install with no problems.
