iPhone

I didn't upgrade to the iPhone 3G when it came out so when the 3Gs was announced this year I was eligible for the upgrade pricing. My AT&T rep called me to tell me about it and put me on the list for the first ones. My new iPhone arrived and it was simple to restore my old information to my new phone and it just worked right away...perfect! Today it was nearly out of battery power so I plugged it into my USB hub and found something disconcerting...it doesn't support being charged through the USB hub. I had to attach it directly to my computer. When connected to the hub, it told me it could sync but that charging was not supported. Maybe I need 3.01 of the software?
