Someone Pls explain differneces between D700 and D710 Epic 4g's

[JohnMcD348]

OK, can somebody tell me the difference between the D700 and the D710 on the Epic 4g? My wife just got hers through Sprint and I am trying to find screen protectors and other accessories for ti but all I find is for the G2 S model D710. Is it still the same phone only one works on CDMA and the other doesn't? I just want to make sure there isn't some kind of unique external hardware differences between the 2 before I buy screen protectors for the D700. I ask, mainly because the stock photos I see of teh D710 online look like a reverse image of my wife's D700 with, what I assume is a forward facing camera on the left top hand side whereas her's has it on the right top. Also, I don't know much about all these different phones. Her's is the slider version of the Epic 4G if that makes a difference.

Thanks
