All good things must come to an end. At least that's likely the case for T-Mobile USA customers who like using the carrier's Wi-Fi calling feature on certain smartphones.
In this week's column, I discuss whether I think AT&T will keep the Unlicensed Mobile Access Wi-Fi calling feature that T-Mobile offers on some of its smartphones. I also discuss Samsung's problem with long delays for Android OS updates. And I explain to a Boost Mobile customer that he has two years to pick out a new phone before Sprint turns out the lights on the existing iDEN network that the Boost service currently uses.
