T-Mobile announced earlier this week that its online sales of the Samsung Galaxy S 4 had been delayed from April 24 to April 29, and now the carrier has revealed that its in-store availability has shifted a bit as well. Originally slated to hit select stores on May 1, T-Mobile's official @TMobileHelp Twitter support account has revealed that Samsung's Galaxy S 4 is now expected to hit select stores a week later on May 8. All T-Mobile stores should have the Galaxy S 4 in stock by May 15.

Samsung recently revealed that "overwhelming global demand" for the Galaxy S 4 has caused some inventory headaches here in the U.S., causing both Sprint and T-Mobile to push back their launches of the new device. These in-store availability delays mean that potential Galaxy S 4 buyers will need to wait longer before they'll able to waltz into a store and pick up a unit, and it's always a bummer to see that happen. The good news is that both Sprint and T-Mobile will begin accepting online orders for the Galaxy S 4 in the coming days, and while it's not yet known when those devices will ship, at least those customers will know that they've got a unit with their name on it (or on a shipping label, at least).
