Woke up on Sunday. Wanted to add some notes with OneNote app on my Lumia and suddenly understand that i don't have any notes anymore. I opened skydrive.com and it was looking like i just registered - clean and empty. Recycle bin was also empty. I lost tons of photos, documents, personal information and i believe windows phone backups also. And by the way, Office 365 refuses to syncronize old notes also.
