If you have a Motorola citrus and would like to install apps to the ad card all you need is the Link2sd app and a sd card with 2 fat32 partitions. And both partitions should be primary. It works great! I have a 32gb card and it's partitioned into a 19.5 and a 10gb. I have 55 apps installed right now with plenty of internal storage left and obviously plenty on the ad card. This is the answer to all your storage problems on the citrus!
