Let see if this helps wioth the bluetooth issue i had on 4.3
If you experience issues after upgrading then backup your docs etc and perform a factory reset or repair as this will often fix issues
Hmm I'm on a Vodafone Z1 phone and havent recieved the update yet. I have checked SUS and SPC but still says that my phone is upto date.
Maybe it still working its way round the UK today?
I don't think so 
Possible it's a Generic phone on Vodafone
same here Karl - I've jsut been to test it. lost the call log feature on the phone, but bluetooth is working fine in the car with steering mounted controls etc. happy bunny.
to previous posters, my phone is from Vodafone, but i dont think its branded as when i dial
*#*#7378423#*#* and look under service info > sim Lock i have all 0 indicating an unlocked phone.
The 0's do not indicate a locked phone - what does indicate a locked phone is the txt before ie: [X] Network 0 would mean locked and 0 tries if the 0 was a 5 etc then that's how many try's you have to enter the correct code - If your phone says [ ] Network 0 then it's unlocked as there's no X in [ ]
