@codl actually #TF and #TransFlash is still used as synonym for #microSD cards in #asia and espechally the #PRC since #SD / #SecureDigital is a #trademark.
Pretty shure #DTAG / #Tmobile has nothing to do with it despite their litigatious ways in literally cease-and-decisting any #telco from using #magenta.
In fact, their "#TeleMangenta" colour #E20074 is kinda recognized as trademark...
