Are you experiencing some issues or something that would make you seek an ETA for a potential update in the works? From what I can see, the T-Mo SGS4 on MDL operates a-ok w/o any hiccups.
I think the OP is making a reference that the Verizon/AT&T/Sprint S4 all received an ota this week that brought apps2sd back to the device, but T-mobile hasn't. It puzzling to say the least.

I read on a t-mobile support forum that they test all updates before releasing any, so they will release it when the testing is done I guess. Who knows when that will be though.
