Googled it and came up with this link to a report on C-Net UK claiming that they actually have the same internals
It might make some sense, considering that Orange and T-Mobile are now Everything Everywhere, that they should both have an arrangement with ZTE around the same hardware - different shells to differentiate them in the marketplace perhaps
Anyway, just thought you might be interested
Word is the Vivacity will be 99 quid and will come with Gingerbread
Sorry if this is old news
EDIT - this link suggests it will have a front facing camera. Do we know that the OSF2 definitely doesn't? And actually I just noticed it has a front search button. Also it looks a bit like an iPhone 4, if your eyes don't happen to be working well, which may appeal to (or confuse) some. Cheap route to iPhoolery might be get one of these and stick a Muuuuuiiiuiuiuuuiii theme on it....
