If you are wondering if Apple is going to join the “fun” with other phone makers in standardization their charger connection with Micro USB, here is a hint Apple is doing it. BTW, did you read about the latest iPhone 4S?
This Micro USB adapter will be available from 14th October 2011. On the Apple page, it says that it can sync and charge the devices with it.
Use this adapter to connect iPhone to a micro USB cable to sync and charge, or to a micro USB charger to charge.
I guess it will be available in UK first as I cannot find it in Singapore Apple online store.
