I decided to open a new thread where we could give some feedback on the new SDK 3_0_3.
The main issue I am having is that you can not upload widgets directly from the SDK, like you used to, instead, you need to create a zip file and upload it through the site each time you want to try it on the phone. Very time consuming for developers!!!
The second thing that is actually related to this is that the dashboard on the SDK is not the same as one on the phone that you are developing on. This makes things confusing as you are still sort of having two accounts.
The third problem I am experiencing is that the graphics of the SDK dashboard are sometimes of a wrong size. It's more of a visual thing than functional.
Finally, I am having problems with the getUsername() in the SDK. It dose not return my user-name like it used to. The function works fine on the phone client.
This update seams like a huge change. Hope you manage to get all of the problems fixed soon.
