In this thread i will be posting tricks and tips regarding s60v3 v5 phones, as and when i find or discover them.
I have come across many questions which are related to these topics so everyone can benifit from it.
NOTE:-Most of these tricks are for hacked phones so when i use words like "enable caps off", "apply open4all patch" etc that means that i'm refering to turning security off on hacked phones and to do those tricks where i mention these words you need to first hack your phone.
So lets start
CHANGE THE DEFAULT NAMES OF MENU ICONS IN S60V3
1)Keep the app in the top left corner of your menu screen. Select any folder and press options so that the option menu is just open.

2)Now without pressing any button or exiting the option menu press the power button (the on/off button) and put your mobile in offline mode


3)the highlight cursor will select on the first icon with the option menu still open


4)you will se a new option RENAME in the option menu now select the rename option and rename to what ever you want
5)You can use various symbol also copy any symbol from text file and paste it using the copy paste function as usual.
RESET PASSWORD OF MEMORY CARD (ONLY FOR PHONES WITH REMOTE LOCK OPTION)
If you forget your memory card password you can unlock it by using this trick,
You can activate this feature from Tools | Settings | Security | Phone and SIM | Allow remote lock menu. The password of your memory card will be your remote lock message.
Define a remote lock password. Lock it by sending a message from another phone to your phone written as password LOCK and then unlock it by sending parsword UNLOCK
Now your memory card will be unlocked.
REMOVING THEMES
Removing themes is a common problem in s60v3 phones. Here's how its done
Do CAPS OFF
Open Xplore or any other file manager. Go to C or E/private/10207114/import. Every folder here contains 3 or 4 theme files(*.ini, *.mbm, *.mif, *.skn). If the folders don't denote the name of the theme, open the *.skn file in hex viewer and you will see the name of the theme. To remove the theme just delete the 4 files of the theme(and not thefolder itself) which you want to delete.
DONE
You can do the same via mass storage connecting the phone or mmc to computer and don't forget to enable view hidden files.
