Panasonic GD87e Software Upgrade?

I have just got a panasonic GD87e, I have had it unlocked and have checked the software its running, it appears its on A22, I know we are on something like A50 now, the phone was only a month old when I got it, I think it must have been downgraded to unlock it.
Can I upgrade it again?
Is it easy to do?
I have a usb data cable!
What is the benifit of upgrading? I've heard 200sms mentioned also someone said I could turn the noise of when I use the camera ?

Any advise / help greatfully recieved


Thanks in advance:confused:

I don't think it's a good idea for flashing especially with USB cable

as once after flashing, u still need to use CB2000 ...but it doesn't work on datacable (unless disabled pin4 &10) or USB cable

if u didn't do the function clear..u might not be able to turn on the phone (not must, but might in some case)

moreover, I do now have 3 mobile phone being killed by improper flashing and need to be repaired..

don't cry if u kill your phone....it's what my comment
