I'm apprehensive to even try that until we know these adapters work perfectly. No one seems to have an adapter thus far even from Ebay, with any feedback.
Have you searched, there are tons on eBay by eBay sellers with good feedback. They are just not shipping until October. I've use generic USB cable I purchased on eBay for the 4 and 4S and they work well. Why pay Apple a premium for them...
