Its funny you mention bcuz i learned a few days ago that it says 8gb.. i also have an 8gb memory card in my Bionic and it totals at 16gb of memory. What they do not tell us is that 4gb are for storage of the apps on our phone and we can not touch it or see it. Thats crazy, so that reduces the internal memory to 4gb, with the 8gb from the memory card only gives you 12gb. But you never get the full amount any storage says. I inserted my memory card with absolutely nothing on it and it still didn't clock all 8gb, it only gives u about 7. Something gb. How is that possible lol.. i don't understand it.
