So I'm about to order Bodyguardz for the touch. I just don't know if the solution can mess up my device (like what if it went into the headphone jack?). If it does get in, does waiting 24 hours help? And can you apply both the front and back at the same time? How hard is it to apply? I also heard that you can't use a plastic case with bodyguardz (heat issue or something) is this true? Thanks in advance!
