I JUST SENT MY FIRST VIDEO IN FOUR MONTHS!
Haha. I know y'all are probably thinking, "Duh.. She didn't do that first?" But no I didn't. I totally forgot about that trick even though I had to do it all the time with my Blackberry Storm.
Anyway, I sent my video at the lowest resolution and only 10 seconds, but that's better than nothing! I will experiment further this afternoon when I take my daughter to dance class. Her grandparents will be thrilled to get some videos of that!
Thank you guys so much for sticking with this problem I've had. Hope the battery trick works for those of you who have the same problem! Keep us updated!
