I just got a used Blackberry Curve, which is pretty old and runs on a old version of bb OS 3.2 and i want to update it to the latest version (like bb7.0 or a bit lesser one is fine). Can I do it? If so how??
The operating system on BBOS 7 probably uses more memory that your old Blackberry even has in total. It would be like trying to cram Windows 8 into an old Commodore 64 computer.
(you might not have an awareness of the old C64. It was considered a high tech consumer item in the early 1980s and came with 64 K of RAM. Windows calculator program probably uses more memory than that.
