Recently I got Error ID: 30702 on my Blackberry.
Initially I suspected problem on BB side, but after researching on the web it is common problem.
Following instructions on this post I’ve tried to login to payment options, but I’ve received same error Error ID: 30702.
Following further posts I logged in in blackberry app world.
Unlike other reports my login was successful.
Then something else was wrong.
Looking at my account I’ve noticed that my e-mail address was unconfirmed. I followed instructions and confirmed my E-mail.
This allowed me to login to my app world gain.
So solution to Error ID: 30702 for me was to confirm my e-mail address.
Lesson learned 😉
