I agree that the look of the interface is sort of a letdown.

Quoted: It feels smooth and fast, although the interface looks a bit dated and mixed. It kind of reminds me to a 1990s Windows desktop manager, specially next to the glossy, ultra-polished iPhone interface. However, there are certain aspects of it which are droolworthy, like the accelerometer-based Google Maps Streetview.

I had the opposite problem; my audio was off all the time. I tried everything, including a hard reset. Finally, doing the following fixed the problem. What a random fix for a bug!

I need to replace my trusty phone after submerging it underwater last night:(

I'll probably go with the Dash.

Anyone have experience with this phone?

Can't say I like the pseudo Qwerty keypad: http://laptopmag.com/News/Cell-Phones/T-Mobile-Shadow-First-Impressions.htm?page=2&image=1

Redotting. This seems very cool although I don't know if it will save me money in practice -- since I don't use all my 1000 minutes every month anyways.

I've been resisting the urge to get the Dash, but this is cool. I'd use it to watch replays when attending live sports events.

Quoted: With the latest update to the SlingMobile software, users of the HTC (T-Mobile) Dash and the Samsung (Cingular) BlackJack can now sling their media to and fro while on-the-go.

Trying to get Opera to work on my SMT5600 Smartphone. Looks like I might be out of luck given that I am paying for the cheap Internet plan.

Quoted: This also means that things like the "Opera Browsers" and basic or old freeware might not be able to surf from your phone EVEN if it's only accessing a website through port 80.

I know some of you have been having problems with your mda's. Maybe this will help?
