Sprint version of Samsung Galaxy S4 already gets an OTA update

You just purchased the Sprint branded Samsung Galaxy S4 this past weekend and already there is a 24MB update zooming at you OTA. There is no official changelist for the update, which probably just covers a number of last minute things that needed to be taken care of. The new build, L720VPUAMDL, is probably being sent out in waves; so if it didn't arrive tonight, there is no need for panic.

By the way, the initial version of the software is L720VPUAMDC. If we might be allowed to speculate for a moment, the only difference in the old software version and the new one is that the last letter has been changed from a "C" to an "L". Perhaps the update flipped the LTE radio on inside the phone, which had previously been set up to work on Cellular only.

You can always try to coax out the update manually by going to Settings > More > System Update. This is not an update to the rumored Android 4.3 build that is now talked about as being displayed at Google I/O so again, we wouldn't lose any sleep over it.
