yes it will!
I did this switch from my 8700g to the new vodafone 8700v case and it fit.
The only thing is you have to be extremely careful with dust getting inside the screen area. Also make sure you DO NOT break any clips opening it up, other than that it takes less than 20 minutes to do the switch.
Another tip is wear rubber latex lab gloves, because finger prints will get on the inside of the screen no matter how careful you are. And it sucks to put it all back together and then realize that you have prints and dust on the underside of the screen.
old case off.
new case before going on...purchased for $17.00 USD off a Hong Kong seller on eBay.
