Hey there streetdreams, i too have been looking for the mobile 6 - 6.1 or 6.5 download as well for the x51 and so far no luck ? all i found is the download for the x51v. i don't know if the wm6 that was made for x51v is compatible with the x51 or not ? i was half tempted to try it but i didn't want to ruin my unit. i'm also looking for a solution / program that will allow youtube videos to play on my x51 but i can't seem to find that anywhere either ?
