So as the title suggests, I'm tired of waiting for the official 8.1 update so I'm going to take the plunge and upgrade to 8.1DP. I have one basic question which I haven't found an answer to but when upgrading to 8.1DP, does your phone get wiped clean of apps, pics, vids, etc? Also, if I decide to revert back (via Nokia Software Updater), will my phone get wiped clean then? Thanks in advance. I can't wait to try out 8.1 and all it has to offer!!!
