How to install a .sis application???

hi.. can anyone help me? How do i install an .sis application to the 6600? I bought an MMC card reader/writer and transferred the .sis file to the MMC card, but then when i switch on the phone and view the files inside the MMC card, there is no .sis file that I have just put in. So what should I do? Thanks... __________________ normaly you install a .sis app with Application Manager; Open this program, select options and press install, select the file on you MMC card and engage install... You can also use PC suite to do this... Normaly the files has to be on the MMC, mayby try to locate it back with you cardreader and pc, if it's not copied proporly copy the file again... Or try to send it through bluetooth or IRda... Mavi forum
