guys.. im planning to buy a desire soon. i would like to know, once i update the firmware to Froyo to 2.2 (official one), can i choose to install all the software into the memory card? or i still need to install it into the phone memory?

Assume that after update to Froyo and the answer is still i need to install it to the phone memory, is there any other software/method which can allow the software@game installation to be be done into the memory card?
