Hi all 
I know the 5140i is an old phone but I love it's functions and ruggedness.
When mine finally died I got a "re-furbed" replacement.
My old 5140i had no PTT funtion, the big button on the R/H side activated the voicetag function (i use a lot)
My new "re-furb" one has this PTT function thing on the big R/H button (i do not need or want it)
Is this a firmware revision thing ? ( I don't think it is a settings thing as I have chercked all the options listed in the menus)
If so, is the PTT funtion an earlier firmware revision or a later one ?
Thanks for looking
