On Tuesday, May 14, Twitter users are talking about Nokia's new Lumia 925 and Blackberry's Q5.  Tuesday, May 14, appears to be an exciting day for fans of Nokia and Blackberry with both smartphone manufacturers announcing the addition of new mobile devices to their arsenal.

Just three months after its European release, the exclusive handcrafted Vertu Ti smartphone is officially on sale in India. Priced at an eye-watering Rs 649990, (€9000) the titanium-bodied Android phone is targeted at celebrities and VIPs and is therefore built more around features than performance -- chief among these being its Vertu Key lifestyle services. These services include a 24/7 concierge, exclusive editorial content, city guides and special, exclusive events and experiences, curated for the user based on his or her passions and preferences.

The latest Lumia is more of an evolution than a revolution but will be a big hit for smartphone owners that put a premium on photography.
