I just got the Invisible Shield for my 30GB video iPod and an iPod Nano, and I'm wondering if there are any tricks to putting it on other than simply applying it to the surface of the iPod. The IS came with a whole bunch of adhesive liquid and I'm wondering what that was for. No instructions were included, so I"m guessing its really easy to put on...but I want to be very carefeul with my iPod and am wondering how or when or if to use this adhesive liquid. Thanks in advance.
