I installed a bunch of apps and I think the EVO has 1gb of space. Just wondering if that's enough available for me to do other things. I want to leave a "buffer" just in case. I'm currently using the Sandisk 8GB MicroSD Class 2 that came with the phone and when I was looking at selling my Touch Pro 2, it turns out that I have a Class 6 Transcend 8gb MicroSD card. I want to switch them out, if I just copy everything from the Sandisk to the Transcend, will that be ok? Or do apps/Android write the data a certain way that I'll have to re-do things again?
