How do I debrand Benq Siemens E71 Please

[starlight2007]

I have the phone currently on T-Mobile UK and im using it with a Virgin Sim.

What i want to do is to remove all of the T-Mobile Branding from the phone itself (software/firmware/icons) and restore it to unbranded E71.

Can anyone supply (or point me in the right direction) me with an E71 Full Flash of the unbranded Firmware to debrand my phone then I can update the phone to last firmware.

Im not so bothered about unlocking the phone off the network as Virgin is fine for me but I want the original icon system on my phone.

Thanks for anyone who replies.
