I think it depends if technology works. To add it just because it's YA will most likely make it seem strange. It may not work if your MC isn't the typical teenager, amongst many other reasons. However, if it can and would work, i'd put some of it in, even if it's not much. It just makes sense, for the most part.
Like everyone is saying, there are some things that are fairy safe to use, others that may become dated. If you want it to be a good representation of now, than add things even if they may go away in a little while. Allusions are often used, and wont hard your book. If you just want technology to be prominent, perhaps it would be better to use your own brand names, or things that you expect will be around for a while. Best of luck, and I hope this helps.
