it is branded, i got some carrier specific apps,and also the bootlogo of the carrier,a french one( bienvenue or something like that).So it must be sim unlocked if i am using orange...

once you sim unlock the phone, it should not sim relock when you flash a unbranded firmware through odin. I hope i answered your question

As long as it's for the same phone model, nothing happens, apart from having an O2 software branded phone!
You'll likely loose root etc also

[Q] Does your phone need to be unlocked to upgrade to unbranded firmware?

Title says it all.. does my phone have to be network unlocked before I install ICS via Odin. I have a Samsung Galaxy S2 locked to T-Mobile UK... we all hate T-Mobile and their ridiculous firmware release dates soo I was just wandering, can I update my phones firmware with it being network locked?
No it doesn't need to be unlocked

You do not need root to flash a stock firmware.. if you want to unlock your phone from your carrier, i suggest you root your phone AFTER you flashed a stock firmware.. there are applications here in XDA that does the job neatly.
I hope this helps
Thanks!! My phone is already unlocked so i do not need root

Its not about warranty, its about development. You wont be able to unlock bootloader and flash custom roms, if you dont care, then go ahead, there are no other differences, since you can flash generic firmware and get rid of vodafone stuff if you want to.

Christ.. Please pay attention, i wont repeat again. You CANT unlock bootloader, and you CANT flash custom made roms, as in the ones you can find in development section. What you can do, is flash generic sony firmware, basically same vodafone rom just without all vodafone apps and branding.

Hi there
I am very sorry i have bad english so It's a bit difficult for me.
Also my knowledge of Android is small.
i have just 2 more questions:
1. the bootloader will be locked forever or maybe in future I can open it?
2. Is the phone supports Hebrew language? Do I need to do something to turn the Hebrew language?
Thank you very much!!
Sorry dont know answers to these questions
