I just had something weird happen today...all my google contacts on my phone were now "SIM" contacts (Sprint phones don't have a SIM card). No matter what I did, what contacts I chose to view, only these would show, and I couldn't edit or delete them. I couldn't sync any new ones on Google either. Luckily a 2 week old Nandroid backup (10 May) saved my bacon. Anyone else experience anything like this? I still don't know what caused it. MD4 Stock Rooted.
