I love the simplicity of my AirCurve but sadly it wasn't useful at all anymore after I upgraded from a 3G to iPhone 4. AirCurve came with adapters for 2 and 3G/3GS but last I checked, Griffin hasn't yet made an adapter for iPhone 4.
So my AirCurve was sad and useless. As you can see in the second photo, the new phone and case will sit in an adapter-less AirCurve if you balance it just right. Set this way it tends to topple over if you look at it funny - usually right into the kitchen sink.
But besides that: since the "fit" is non-existent there is no volume boost as the sound from the iPhone speaker is not getting funneled into the AirCurve's sound channel. What to do?
SUGRU to the rescue!
It's specifically designed for hacking your stuff.
(What is Sugru and where can you get some?
The original phone holder/adapters that come with the AirCurve are a flexible rubber.
Sugru cures into a flexible silicone rubber and you can mold it into any shape you like.
Perfect for making your own holder/ adapter!
(The AirCurve is a non-powered volume amplifier made for iPhone 2 & 3G/3GS, you can check it out here
. Sugru is cheap and has endless uses! I had a super 12 pack shipped from the UK to California for $16 total. This hack cost about $2 in Sugru.)
