It launched way back in September and we got a hands-on with the handset not long after. But since then? All has been quiet with the Nokia E7.If you missed it (or have just forgotten about it), the Nokia E7 is described as 'the ultimate business smartphone', with Microsoft Exchange ActiveSync on board for access to corporate email inboxes. It's also got a 4-inch AMOLED capacitive touchscreen display with Nokia ClearBlack technology for improved outdoor visibility, a full, slide-out keyboard, an 8-megapixel camera with HD video shooting, GPS with free maps and easy access to your social networks. As you might expect, the platform is Symbian, specifically Symbian^3.According to Recombu, the handset is heading to O2, with a holding page now confirming that very thing. It's simply down as 'May', which doesn't offer us much in terms of specifics or indeed price. It's also later than the dates being given by sim-free stores, suggesting a further delay for the smartphone.But if you want one of the last big Symbian launches before things go Windows, at least you've got an approximate timescale to work to.
