upgrade from os 4.5 to 5?

[ykun]

is it too late to upgrade my th-55 from v. 4.55S to 5?

never bothered to until now, but am interested in a program requiring v. 5 and above.

If yes, where can one get the upgrade? Tried the sony and palm sites, but couldn't find information
thanks

if you talk about the OS.. you already have PalmOS 5.2 in the TH55.. where did you get the 4.55S info?

thanks for setting me right :p
