@vgrinshpun
plz post a) prior firmware version, b) OTA or svc center, c) wifi or not if OTA.
If anybody else reads b4 posting that may eliminate a bunch of noise. Or maybe not.
Prior firmware - 5.12
OTA via 3G - Was originally planning to download it at home tonight (thought that this is elusive V5.14), but when saw a newly released iPhone app mentioning V6.0, I could not wait - downloaded via 3G
