I feel the same way. As I tried and failed to stream flash content today (yes im aware there are roms, workarounds, etc) I thought about contacting both at&t and samsung just to let out my frustrations... sigh..
I would have to agree with ballistic. The problem lies with both Samsung and the US Carriers. All of the US carriers have updated a number of their phones to Froyo and Samsung has updated its worldwide (not US) Galaxy S phone to Froyo.
