I got to play more with my Nokia 5800 XpressMusic (XM) phone in the weekend. The following are the things I tried.
1) Video playback: I found there are some Nokia sample videos and a .wmv video (transferred from my PC Windows media player). Both played without problem. However, when I copied some Apple Dev movie (mpeg-4 format?), it only plays the audio.
2) Game: the Bounce game comes with the phone is a bit challenging for me, as you may know I don’t play computer or smartphone game often.
