| | Unlocked BB used with another carrier
Please Login to Remove!
I have recently got a BB Pearl 8120 sold by an specific carrier so my first step was unlock it in order to use with my current carrier (who not sells this model). Now, I'd like to upgrade firmware to 4.5 so my questions are:
- Can i use a firmware version provided for a carrier different than mine (mine does not sell this model)?? I yes:
- Do I have to unlock again the device once i've upgraded the firmware
I am trying to create a BIS account but when I join the PIN and IMEI, rim site tells me that the device and the selected carrier do not match. How can I solve this? is there a way to "unlock device in RIM site"?
Thanks for your help
