iPhone Duo display feels soft above the hinge and can wrinkle

Reviewers found that the iPhone Duo's inner display depresses under finger pressure right above the hinge and forms temporary wrinkles. The softness appeared consistently across several test units, suggesting an intentional design choice rather than a defect. Official sales begin October 23.
