Just got a BB8330 from Sprint and added the 8gb card. I am running 4.3 OS and it found the new memory just fine, but it still will not allow large downloads. I am trying to get files in the 1 to 5 meg range, so I am not going beyond the size of the card, but the documentation is a little vague on how to do this. Has anyone been successful in setting their BB for this? Thanks in advance.
