The Nokia 5230 is an entry-level smartphone, and this becomes readily apparent with media playback.
It's just too difficult to find music and movies, and the Ovi store is still a work in progress (at times, the Ovi apps even failed to open the store at all).
Lacking the Apple iTunes store or a robust partnership with Amazon for buying songs, the Nokia 5230 is just an average media phone.
Playback quality for music was fine, but videos tended to stutter a bit due to the slower processor.
The phone has a 3.5mm headphone jack and comes with a 4GB microSD card – which is expandable up to 16GB.
If you do load up a bunch of songs, the music player is just adequate – it lacks any useful album cover viewer (you can view album cover art but you can't flip through them like you can on the iPhone).
There is an FM radio on the Nokia 5230, and it worked well for several news and sports channels, but the music quality, even on earbuds, was just passable.
You can record voice memos to yourself, but the Nokia 5230 lacks the advanced features of, say, the Nexus One in terms of easily sharing these memos when you connect to your PC.
