So, I've been using S2u2 for quite some time, since 1.37 or so on my Touch Pro.
Over at XDA, someone has created the "Touch Pro" edition of version 1.50d, the newest version. The Touch Pro Edition has either a black theme or white theme, with the flip clock that we have for TF3D.
I must say, the difference between 1.45 and 1.50 is NIGHT AND DAY.
This application now works like, in my opinion, nearly as fast and snappy graphics-wise as the iphone.
You need to make the switch NOW. I'm not even kidding, this is what I always expected S2u2 to work like.
Kudos to A_C and dharvey4651 for such a great working and looking app
Don't forget to follow Dharvey's instructions on how to clean your TP of old versions before installing, I bet it makes a big part of the difference too.
