I have a file with maybe about 90 pictures in it that I want as wallpaper. Would be much easier if I could just drag those off the laptop (Vista OS) onto the phone.
Or do I need to get a memory card to transfer that file?
Well an SD card would be an extreme benefit for you, any Blackberry user will tell you that. 4GB mini sd card would be sufficient enough for the standard user. Although you can go higher in the Gigabyte realm if the price suits you. In order to get the pictures on to your device you must use the Blackberry Desktop Manager. Load the software on to your pc. If you don't have the cd you can download it for free from here:
if the sd card is in it
then yes
you will be prompt about media something something when you plug it in
click yes n look at ur screen for autoplay
Enable Mass Storage: Click Yes. If your computer is bluetooth enabled, you can do it over the air as well, but it's slower. It is a nifty tool to have because your friends will trip when they see it.
