My brother has the Curve and he can play the voicenotes he sends his friends on the BB messenger. I have the Pearl. When I send a voicenote, it just shows voicenote sent in green. It does not have the option to play it like when I am sent one from a friend. Can I change some option or is that just one feature that the Curve does better than the Pearl?

That is a feature on the Curve as well as saving the voicenote. You should be able to open your sent message and play the voicenote.

I clicked the menu while on the conversation on my BB messenger and there was no option to play my sent voicenote... any ideas?
