Treo 700p can't beam to Treo 650

[osteord]

Any ideas why my Treo 650 gives me "Data accepted in unknown format" message when my friend tries to beam me a memo from his Treo 700p? Another friend gets the same message when I try to beam him an mp3 to his Treo 600.

Are you using the same player on both phones? There are several music formats, and its possible you just need the right player, otherwise, I'll sit back & wait for the right answer.....

Thanks for the reply,

I'm not sure which player he uses on his 600. I'll have to ask him.

Any idea why my 650 can't receive memos from a 700p?
