True to their word, within a few days the case appeared on their website and I put in my order just before Christmas. I didn't expect the package to arrive until the New Year, but half way through January there was still no sign of it. I contacted Joby through Twitter (@Jobyinc) and they replied to say they would look into it but could I email their service team. This I duly did, and within a few hours received an email explaining that the item had been sent on the day of order, but had apparently got lost in the post and a replacement would be dispatched forthwith.
A couple of days ago the iPhone case arrived and I would definitely recommend it to anyone with an iPhone and Gorillapod (especially if you've also downloaded the Gorillacam app also described in the post).
Whilst the suction pad I had been using worked OK, it did require a very clean surface, and was not suitable for anything too rigorous. The dedicated case provides a much more robust connection to the Gorillapod, and the iPhone simply clips into it with a very snug fit - in fact so snug it can be a bit tricky to get it out in a hurry. The good news is that the case fits flush on a flat surface. The case can be purchased direct from the Joby website and costs £14.95.
It's worth noting that I would not consider this to be a replacement case for an iPhone. It's better than nothing, as it is sturdy enough, but it doesn't provide the depth of protection that I look for in a permanent case.
I'm pleased to award the first Apple Harvest service award of 2010 to Joby (sorry guys, it's a virtual prize), for their swift and effective response.
