Microsoft “Pink” – answer for Apple iPhone ?

Microsoft and Verizon will be partnering together to launch a touchscreen multimedia smart phone. Its code named “PINK”. It will have an some additional features of Windows Mobile operating system [obviously] and Zune capabilities [as expected]. 

Microsoft will not make “the phone” but only provide the software. It is also said to feature Windows market place as a part of the phone [lets see it somewhere, we always keep talking about it]. Why can’t they just call it Zune phone or why can’t it be blue instead of pink?
