Is there a brand specific micro sd card that will go well with this Droid 4? I am looking to get the 32GB but there are different versions and different prices....Patriot PSF32GMCSDHC10 microSDHC Flash Card - 32GB, Class 10 is one that I was looking to get... but is it compatiable.... I know nothing of the different SD cards and what they do other than hold information... So what is a microSDHC Flash Card and does it do what I need it for in the Droid 4.... and what should I be getting? Thank you..
