Have you noticed increased stability post NoDo? I have a 8gb card that I was using previously but then the phone started randomly resetting so I yanked it. Trying to decide if I should give it another shot or wait to see if the supposed Focus firmware update will address the issue.
I also held off from installing an 8gb card.I updated to NoDo the night it released. And Last night I installed an older Class 2 8gb SD HC. Reformatted the phone, loaded all my stuff back, which sucks cause you have no option of using the backup that NoDo creates. Your phones is bascially recognized as a new device. I loaded it with about 5gbs of music (14.59 total. 9.52gb free), and so far no problems, hopefully I never have any. Since I never had the issues of it reandomly resetting, I dont know if the firmware issue was fixed.
