Smart Phone by Blackberry. Operating System is awesome. Does not need Blackberry Plan as Data Plan is sufficient to run all the Blackberry Apps. Smart Move by RIM. Always recommend to use BlackBerry Smart Phone. Overall I am happy with this product and its performance.

Snapdeal has shipped me a swapped handset. It has no warranty certificate.
