It's been noticed this morning that a new firmware version 62.0.A.3.70 is being rolled out to Xperia 10 iii handsets, which fixes the Play Store security updates stuck bug amongst other things.
Personally, I havent been given it yet, probably because i'm running branded firmware (O2 UK) but hopefully it wont be long.
If you have been able to download and install it please let us know in this thread of any changes you've noticed since the update or of any issues you encounter.
