joshuacalvert writes "I work at a company that has a small influence in the future functions of a cellphone company — including some of the larger wireless providers. What kind of API should a cell phone company offer to its customers, and especially to Android/iPhone app developers? One famous example is Blackberry's unusual "push" email service which is unfortunately proprietary. Another might be a precense service, a backup-service. It would seem that many of the most useful phone interfaces are things like GPS, accelerometers, mic/video, which are independent of the provider. So is there something cool the provider can add that you would really love to see implemented?"
