We've been through this before. This notice has just landed in our inbox:
Apologies for the late mail, but due to the expected weather in New York, T-Mobile will be postponing its showcase event (which was scheduled for October 29) to a later date. We will keep you posted on a rescheduled date as soon as we can.
Thanks for your flexibility and patience and apologies for the inconvenience.
The weather is getting nasty out there, and T-Mobile has decided that holding its event in New York Cityisn't the best choice. Since Google has also decided to postpone its impending Nexus event, we're not going to blame T-Mo for taking the safe route. No reason to risk having extra people traveling in Hurricane Sandy.
