The CEO of struggling handset maker BlackBerry (BBRY) wants to reassure users that the company is moving forward and will still be around to support its devices.

BBRY has already run ads in prominent newspapers in the U.S. and Canada hoping to stem user defections to rival platforms, now John Chen, who was recently named as its new chief executive, has issued a letter to BlackBerry users:

To our BlackBerry Community,

As you know, this is a time of significant change at BlackBerry as we accelerate our efforts to transform our business.

I know there has been a lot said about BlackBerry, but let me remind you that at BlackBerry, we are not dwelling on the past. We are looking towards the future.

We Are Committed to Reclaiming our Success

We have begun moving the company to embrace a multi-platform, BYOD world by adopting a new mobility management platform and a new device strategy. We are also leveraging our tremendous assets, including BBM, our network and QNX. While we are proud of these accomplishments, we know there is more work to be done.

I know that it’s going to take time, discipline and tough decisions to reclaim BlackBerry’s success and we are ready for that challenge.

Our Commitment to our Customers Remains Unchanged

We remain committed to delivering high quality products and services to the millions of people who rely on us globally. We also want our customers to know that BlackBerry has significant financial strength for the long-haul.

I believe in the value of this brand. With the right team and right strategy in place, I am confident that we will rebuild BlackBerry for the benefit of all of our constituencies.

We are Excited for the Future and you Should Be Too

Thank you for your strong support and continued commitment.

Sincerely,

John S. Chen

Executive Chair and CEO

Last month, BBRY announced that it was not going forward with a $4.7 billion takeover bid from Fairfax Financial Holdings. It also said that former BBRY CEO Thorsten Heins, who led the company through the launch of its BlackBerry 10 operating system and devices, which failed to generate consumer enthusiasm, had resigned.

BRBY shares fell modestly in Thursday morning trading.
