i filmed some video with my bold 9700, it played fine on my phone but when i gave it to a friend who has a pearl ... (not sure what model) they get an error... unsupported format. i have gotten video from them and watched it no problem on my phone, and the file is def. in 3gp format. they are able to watch video that i made with my old lg phone as well as the video they have filmed themselves... but not the one i made on my bb. so what gives, i'm not very tech savvy and can't find a solution on the other forums. anyone with ideas please help!
