I can't get an iPhone charging cable until sometime later this month... damn.
All the stores have tons... Did you even try?
I've tried my local apple store twice, and best buy 3 times. And nothing. Yeah, they get them in on a reg basis. But they're gone as fast as they get there.
You can also order from Apple.com and get them within 2 days. (regardless of the shipping estimate..mine said mid-october, and I got them last Tuesday).
And I bought 4 at my local Apple Store last Sunday. They had tons.
Tons at at&t store and the Apple store in my area
Did you try any of the carriers that have stores in your area?
Do you know if they also had the adapters for the old 30 pin cables?
I ordered mine online at Apple and they came the next business day.
