i would like to share my impression so far about my first blackberry phone as i have mentioned in the title. My BB bold 9900 is a nightmare, as i used my device and attempted to create an BIS account, i got the 507 error and for resolving that i searched all the web but didn’t find any solution for the same. I have tried my best in order to make a BIS account through the phone but unfortunately i was not able to get it created. Any suggestion for resolving this? thanks in advanced.
