BlackBerry Smartphones have become the must-have tool for people to conduct their lives in a more streamlined manner. Since the launch of the 850 two-way in 1999, BlackBerry's popularity has grown vastly in the business world because of the features available such as Phone, Internet/Intranet Browsing, Personal Organiser SMS/MMS & Instant Messaging through bbm and Email.
You will need to know the exact model or series of BlackBerry smartphone you have, as the reset technique is different for many of the Acer units. If you are unable to locate the model information it can normally be found inside the battery compartment.
Once you have this information, just select your unit from the BlackBerry Smartphone Model list, and follow the reset instructions exactly.
