DashCommand for iPhone with OBD WIFI

[Action140]

So I'm wanting setup my iPhone with DashCommand, and I think I've got it worked out but I just want to make sure. My car is the alloytec SV6 and I've had a look around and found this:

App Store - DashCommand - OBD-II gauge dashboards, scan tool, and vehicle diagnostics
and
eBay Australia: Buy new & used fashion, electronics & home d

Are there any cheaper or better performing devices? Will it be just plug in and play or is there some configuration needed that I should be aware of?
Any comments are appreciated

There might be cheaper, but if this is the route you are choosing, then the PLX wi-fi device is by far the best of the lot

And dash command is great software

If you want to save a bit of $$$ and your a little techie and you have a iPhone 4 or below (because iPhone 4s jailbreak is not out yet but should be soon) you could use this software

with a bluetooth OBD2 reader (much cheaper than wifi) and you would be sweet.

I have the Torque app on my samsung galaxy s2 phone linked via bluetooth to an OBDII module and works a treat.So many different guages you can add.

To the people that are using bluetooth, has anyone experienced delay problems? I read that wifi was better because it had a quicker response time. Is that true?

There is no perceptible lag using my cheap bluetooth unit

Or you could use this.
