I have read about some usb woes here and to be safe a charging dock looks like a good fit for me. I sync wireless with bluetooth. There are a couple for the curve on the blackberry site one charges an extra battery at the same time. The site does not really show if the chargers work with a usb or an adapter for the wall outlet. I would prefer the wall outlet instead of the usb. Any tips and which one fits my needs best...also it seems that ebay has them cheaper better,worse or the same chargers?
