First you have to transfer the file to your phone via Bluetooth, IR or E-mail
You will then receive a message containing the file as an attachment.
Highlight the attachment you want to install, bring up the options list, and select install.
The file will then be saved to your phone's memory.
Ensure you delete the original message once it is installed on your phone, as this will consume memory.
When installing a SIS file, as long as PC Suite is installed and the phone connected
to the COM port in mRouter (which should be in the taskbar), you can just double click
on the SIS in the PC and EPOC Install installs the program on the Phone, without having
to send it to the phone first. This is a good way to install software if the memory is nearly full.
