I think these smartphone and internet is part of a larger issue of many in the charedi world wishing some sort of life back to the Shtetel, Like it was some glorious place. No amount of fasting, tzdekah and praying will bring back that life and the gloryfing of the Shtetl seems to only harp on the positive side , not the Pograms, the severe povery and other really bad things that happend there.
Being we are here, we have to adapt and failure to adapt will have consequences, exactly what those consequences (Both positive and negative) are may not be apparent at this time and may not be known for a few generations.
Just throwing this out and not saying this will or wont happen. As charedim become more and more of a percentage of Israel and a majority at some point, the secualarists could leave turning the country back time to an agrian economy, however one before modern time and food shortages would become common and perhaps Israel would become one of these places whose economies depend on foreign aid and the benevolence of other countries
