A number of operators have announced support for devices powered by RIM’s anticipated BlackBerry 10 platform, which are expected to be available from the first quarter of 2013.

UK operator EE has said it will sell the devices alongside its “4GEE” LTE services, and smartphones will also be available via its T-Mobile UK and Orange UK brands.

According to TechRadar, 3 UK and Vodafone UK are also set to offer new smartphones from the vendor.

And on the other side of the Atlantic, Canadian operator Rogers Communications has begun taking pre-orders for the new devices, although it notes that full details “including pricing, availability and specifications” will not be confirmed until early next year.

While there has been some positive momentum around RIM in recent weeks, as it nears the launch of its next-generation devices, the company is expected to announce another set of poor quarterly results later this week, as its existing device portfolio struggles to find buyers.

The company will need to ensure investors and analysts that it is effectively managing its financial position in the near-term, ahead of the release of its new smartphones.

One RIM shareholder described its next set of numbers as “the most important in the last few years”.
