Livestream app problem

My brother was very upset when he found out that his Blackberry wouldn’t support Livestream. So his birthday is coming up, and my sister-in-law and I are trying to figure out what we can do. Is there any way to get another phone-- or some kind of device-- just for apps like Livestream? He does like a lot of features about the phone he has now, and he keeps saying that he can’t have another non-flip phone, but I can’t stand hearing about the Livestream problem anymore, and neither can she. All opinions appreciated!
