    I Just got a 8520 for my wife and she enjoy it very much!
    OS is 4.61 and all work fine.
    I personally have an 9700 with the latest OS and IT IS GREAT.

    Is there a real need to move from 4.61 to 5.0 on 8520?
    What are the Pros and Cons; speed,new features,reboot time,battery etc....
    Is 5.0 for 8520 working well and stable?
    Is the best one to load? Or there is better like 592?
    Thank you very much for your help

    there are actually several pro, and on my opinion you are better of upgrading it to OS5

    battery live is much grater, reboots are faster. it's better overall. upgraded several people's blackberry into os 5, and none complains...

    try it for yourself.

    509 is the latest official...
    592 is the latest. but keep in mind, some devices have trackpad issue with os after 509. such as mine, it simply don't work. but tries the same os onto other device, and it worked fine...
