T-Mobile USA CTO Neville Ray provided a potentially major clue to a possible iPhone deal in an interview late Tuesday. He divulged to CNET that he had seen Apple's cellular chipset roadmap and that the next chipset would support AWS (Advanced Wireless Spectrum), or the 1,700MHz band that T-Mobile needs for its HSPA+ 3G network. While cautioning that no deal was guaranteed, he made it clear that the company's most often cited obstacle was now just temporary.
