The BlackBerry Slider has been rumored to be released this coming quarter and unlocking the BlackBerry Slider will probably be very similar to unlocking other phones made by RIM (the makers of BlackBerry phones). Like any GSM or SIM based phone you will need an unlock code to unlock your phone. You can usually attain a free unlock code by calling up your phone carrier and requesting one. In exchange they will want your BlackBerry Slider’s IMEI number which you can get by typing *#06#. There are also no official prices on how much a pre-unlocked BlackBerry Slider will cost, but like many phones I suspect it will be cheaper to unlock the phone yourself. Please note the free instructions below have not been tested as this phone has not been released yet. But they tend to work on most BlackBerry phones.
