The Nokia 5610 XpressMusic has just gotten its approval from the FCC. A mid-range slider style phone that is music-centric, the 5610 is an upgrade to the current 5310.
Improvements include a better camera, now at 3-megapixels and up to 18-20 hours of music playback. No word on pricing, availability date or carriers. Possibly this will be sold directly through Nokia.

Nice phone, with good design, lighter than its father (6500 slide) and offers good quality of music especially when in headphones, that's why it's an XpressMusic phone. Its built-in loudspeaker is not that great by the way. It has an anti scratch screen protector, but it will be hungry for thumb marks so you need to clean it always. Since the nokia 5610 phone is the only S40 5th edition phone, it has limited applications only. Some bug fixes were made and camera fixes were done in the 8.30 firmware making it better (depending on region). It has a decent 3.2 mp camera for its lineup which is far more better than 1st generation N-Series phones.
