Unlocked pulse and December update

[Guest campdave]

I've bought a pulse from eBay that's already been unlocked. When it arrives, I'd like to apply the December update. Presumably this won't affect the phones unlocked status, as I'd like to use a three sim in it.

Thanks for the help

It'll stay unlocked no matter what software changes you do.

That's the answer I wanted! Thanks
