I have a T Mobile Android phone but even though I have installed a 8GB SD Card, I cant d/l any more apps or updates because of 'insufficient memory'!

I'm new to Smart phones & am getting really frustrated with this aspect.

Ive deleted as many apps as I can or tried to move them to SD card manually but the problem still remains

Help!

How are you moving the apps? I assume you are using Android 2.2 or later?

I also assume you are using Settings > Applications > Manage applications then selecting an app then using the Move to SD card option?

You can also try Apps2SD from Play Shop/Market.
