Picked up a 5230 at weekend, its definitely an interesting device.
Even though the firmware is definitely a lot more polished at release than that on the 5800, its still a little irritating.
So far ...
- alarm - can't switch it off! You have to go in and remove the alarm, not recommended first thing in the morning
- music player volume - only works when you're in the music player. If you've got music playing from the home screen, the volume keys do absolutely nothing.
- music file management - delete a track in the browser, it goes back up a level. It should keep at the same level.
Everything else so far seems absolutely fine. Sound quality for music is definitely better than any of my previous Symbian phones, through the same headphones (Sony in-ear devices)
