I put Task Spy on my phone and a restart phone aplication. Now is very easy to stop a program, but i can't stop antivirus. I will tray to stop from antivirus settings.

I read a lot of things about firmware version but now i able to find my firmware version
Try *#0000# code to see your software version.

I pun Agile Mesenger on both mobile Nokia 7710 and Nokia 3650 and all version (Series 90 and Series 60) work very fine.

On my N7710 I install TaskSpy, Metro, a few games like No Man's Land and SuperMiners, a little aplication for restart mobile, more safe without remove battery.

In next few days i will post few links for download nokia 7710 software.
