Ok, so why does my phone have so much space used by "other"? wtf is it? I've had a lot of JB tweaks before i upgraded, could that be it? Or app data for uninstalled apps? Thanks a lot?
Texts and app data fall under that category if it's a freshly restored device. If it's a jailbroken and tweaked device, then your Cydia apps will fall under that category as well
