This dock SUCKS!
FYI-- I'm using the Captivate on the AT&T network.
After many months of waiting on the back order, the desk top cradle arrived today, and...
it's simply awful.
While docked, you're stuck with five icons (Alarm, Daily Briefing, Gallery, Music and Voice Search). They are not customizable and I rarely use any of them. Samsung thought it sufficient to only allow customization with the clock (you can turn it off or get an analog or digital version--- WOW!) You can also change the city and the Celsius/Fahrenheit in Accuweather. My experience has been that Accuweather is wildly inaccurate. Totally useless...
As if that wasn't bad enough, Samsung, in their infinite wisdom, designed the dock so the volume controls and the headphone jack port are blocked. Finally, you can't access contacts or make calls while docked. That's right, you can't use your phone to make a call. To place a call, you have to first exit the landscape mode by pressing the home button and you're then in your home screen. But of course, at this point, everything is sideways if the phone is still docked. Pretty ridiculous if you ask me. I contemplated returning the dock for a refund, but the return policy included in the packaging states that full refunds will only be given for unopened items. Samsung states they will make partial refunds (at their sole discretion) based on the condition of the dock, accompanying literature and the packaging.
Learn from my mistake-- This dock is a huge waste of money. I've had it with Samsung. The delays and poor quality of the dock, the delays with FROYO and overall poor customer service means I'll be looking to purchase my next phone from another manufacturer.
