Now, the "un-carrier" (as it is now branding itself) has revealed that it is pushing online availability of the Galaxy S4 back to April 29. The move was due to what T-Mobile is calling an "unexpected delay with inventory deliveries."
T-Mobile's statement, in full:
We know customers are really looking forward to getting their new Samsung Galaxy S 4 soon. However, due to an unexpected delay with inventory deliveries, the Galaxy S 4 will not be available on www.T-Mobile.com as planned on Wednesday, April 24. Instead, online availability is expected to begin on Monday, April 29. We apologize for any inconvenience and are working with Samsung to deliver the device to T-Mobile customers as soon as possible.
The date change does not seem to have affected T-Mobile's pricing options for the smartphone. The Galaxy S4 will be available on the carrier using the company's new pricing scheme, which requires only $150 upfront, plus monthly payments until the full cost of the device is paid off.
