Make sure that the app's are for your make of phone first.
When you have downloaded PC suite, then you should just click onto the application(s) in question and then it should auto load onto your phone, though you will be asked some questions, just read the instructions as and when the applications load onto your phone. If you have a micro slot for a memory card then get a 4gb one, and when you are asked to where you want install the app in question, select the 4gb card, usually this will be marked "E". Once the application is installed find out where the app is on your phone. Enjoy
