I have an Optimus V (the One,M,S,T,and V are extremely similar and use an ARM 6 processor). Mobo Player works fine. I use BS Player Lite because it can be moved to the uSD card.
There is not as much support for the T as there is the M and V (Metro PCS and Virgin Mobile).
Metro PCS has come out with the M+ which is looking really good. Virgin Mobile has come out with the Elite which is just as good.
The LG Optimus T is old an slow by comparison.
