After hafing voip support on some 5700 series models I expected voip on my new Nokia 5800 XM model but was disappointed when trying to configure it. Since I also found a petition of about 350 owners who ask for a firmware update with voip inclusion which is being presented to Nokia without result, I will give my Nokia 5800 XM. Thank god I found out soon enough, bad luck for the vendor. I thought development tries to get better things and services but are suprised by Nokia regarding development as something backwards oriented.
