For example, in the U.S. the Rose Gold iPhone 6s Plus is shipping in 3 to 4 weeks for T-Mobile customers in 16GB, 64GB and 128GB versions. At AT&T and Verizon, 3 to 4 weeks is how long it will take for your 64GB or 128GB Rose Gold iPhone 6s Plus to ship. All other iPhone 6s Plus models ordered from a U.S. carrier will take 2 to 3 weeks to ship. That includes all Rose Gold versions from Sprint.
If you’re looking for the smaller-screened Apple iPhone 6s, you are in good shape. For the most part, every color in every storage option will ship September 25th, the original launch date. The only iPhone 6s models that have a delay among major U.S. carriers are the Verizon branded 64GB/128GB variants in Rose Gold. Those will ship in 2 to 3 weeks.
In China, all iPhone 6s Plus models will ship in 3 to 4 weeks and all iPhone 6s units will be in transit in 2 to 3 weeks. Based on shipping dates, the Rose Gold iPhone 6s Plus is also under heavy demand away from the U.S.
