Hi!! I've got this problem with my N9.
I went to config -> Restore-> erase device. so the N9 took 15 minutes to erase all data. But when i turn it on, all the applications downloaded from ovi store weren't gone.(they are still working in the device) And either i can't erase these app. nor install new ones...
I erased 3 times the N9 with the same results.
any ideas what's happening?
