i am using telerik app builder free account but 30 days trial expired,,, i have created android package but can't create iphone package...
Problem: Cannot find a valid Ad Hoc or Development provisioning profile that matches the application identifier you have set for your app. Click Options to manage your provisioning profiles or close this window, open the Properties dialog, and set a new application identifier for your app. This will cancel the current operation and you will need to run it again
Try intel xdk...or phonegap buil pakage....try to read full documentation on phonegap....because telerik will let you create "debug mode" apk for android not release one....
