This is my first post here so hope I did everything right :)
I ordered one of these phones from Phones4u yesterday and it arrived this morning unlocked! :)
It doesn't say anywhere on Phones4U that it's actually unlocked but mine definately is as I have just tried my Orange sim card and it works.
These are brand new, boxed and sealed. There is no branding on the phone or the software. The colour is also black, not silver as shown on Phone4u website.
If you are thinking of buying one then make sure you get the T-Mobile PAYG, the one in the link provided, else you may end up with a branded and locked phone.
They are currently in stock online.
Edit: There IS T-Mobile branding in the software but not on the phone itself.
