Main Memory or Storage Card
 

Is there a difference (in speed or anything else) when programs are stored on the storage card instead of the main memory? is there a rule of thumb to decide when to install on the device or in the storage card?

Thanks, MC NOOBE:headbang:

Certain apps will require you to install on the main memory. In performance I don't any difference in speed install one way or another. General rule of thumb is, if the app is running on the today screen then it should be installed on the main memory for it to function properly or at all.

In addition to today-screen plug ins, anything associated with your outlook data or your phone (including ringers) traditionally needs to be internal, not on the card.
