I'm interested in installing mobile banking apps on my blackberry to access my bank accounts, but I'm concerned with security.

I have windows mobile 6 and I want to get some apps but I am not sure how much space they take up. I have been looking at 4gb and 8gb micro SD cards. Would 4 gb be just fine or should I go for 8?
