This phone is great on the surface. It plays music. The battery life is good. It can browse the internet. It has a 3.5mm jack. It has GPS.
When you start to play with it though it becomes apparent this phone is riddled with problems. Nokia seem to have forgotten this phone. Very few apps on the Ovi store are signed for use on the 5230 even though they are absolutely compatible. The latest firmware seems unavailable even though it's out there somewhere. Browsing Nokias site and apps allot of the time this phone is missing from lists in which it should definitley be contained. I.e It is not even in the NSU check-list. Something every Nokia phone on the market should be on! Visiting the forums shows me that allot of people are having various problems.
So to sum-up. The built in features on this phone are great, They work. It works out of the box. Music, GPs, SMS, Phoning. Just don't expect to make use of this as a true Nokia Symbian S60 phone or receive much support with it.
It works but Nokia have forgotten this phone.
