I'm so please to say that this product fits the LG Optimus G 2600 (E971) sold by Rogers in Canada.
I wasn't quite sure this would fit my phone because it says it's only compatible with Sprint's version and someone in the Q&A said it's not compatible with Rogers version. I contacted OtterBox's support and I was told that it should fit so I bought one.
It perfectly fits the phone! All buttons are working properly with the case on and both power & headphone jacks are protected & available after lifting the rubber port cover.
