On DIWALI occasion, I purchased BlackBerry Bold 9700 smartphone and I found lot of best features on it. It features 3G, 2.44″ TFT display, 3.15 MP cameras, Wi-Fi, GPS, and Bluetooth. The RIM BB Bold 9700 carry T-Mobile its first 3G BlackBerry and improves on its predecessor and more power. I use it for internet surfing and playing online games. Yesterday I did BBM upgrade process and it shows successful downloading message. But after that it shows error message. Message is “BlackBerry Messenger failed to register with the BlackBerry Messenger service”. What should I do that works to solve registration failed problem. I expect lot of information coming from your site.
