Whatever the words of the Rav are irrelevant in the fact that texting is good or not good, we dont need to know what he really said or didnt said what we need to know is:
Do we want our bachurim to have access to anybody through texting? Should we encourage people idle time instead of learning? What is a person going to gain from texting?
We have to think very hard and seriously . Is it good or no good.?
