The 128GB version will cost you $50 more, while the 256GB one will set you back $900. Prices could vary a bit depending on which carrier you choose -- it's available on AT&T, Sprint, T-Mobile and Verizon -- though you could also buy one unlocked and just activate it later. The phone will ship starting on October 26th.
