Yeah all of HTC's phone have been renamed to T-mobile something...I.E....
HTC Herald = Tmobile Wing
HTC Wizard = Tmobile MDA
HTC Juno = Tmobile Shadow
HTC Excalibur = Tmobile Dash
That is only for the US, other countries have different phone names...Like the MDA Vario, XDA...and what not.
But i think that is the case for most of HTC's phones...The HTC Kaiser is also known as the Mda Vario III, HTC TyTN II and AT&T Tilt.
The HTC Wizard is also known as the Qtek 9100 / I-mate K-JAM / MDA Vario / O2 XDA Mini S / SPV M3000 / Cingular 8125 / T-Mobile MDA / Dopod 838 / VPA compact II
The HTC Herald is know as Tmobile Wing and HTC P4350
So even HTC has different names for their phones!
