Are u sure its not working after following shahz tutorial (very good tutorial, kudos shahz)? Does ur internal memory still decrease a lot after installing apps?
In the sdcard setting menu. it will not show your ext4, only fat32 will be shown. So you will not see any info on your ext4 app partition.
Two methods to see if you got the App2SD working or not:
i- if u have linux machine (the one that support ext4 if u format ur sdcard with ext4) u can just plug in the usb cable to ur phone and the ext4 partition will show up. Inside that contains an app folder and u can check if the program u install is in there or not. If there is apps in there, that means its already working.
ii- if u using windows, u can check via adb shell. follow the code bold below:

C:\Documents and Settings\Fiskall>adb remount
remount succeeded
C:\Documents and Settings\Fiskall>adb shell ls /system/sd
app app-private lost+found

Just so you know, even with App2SD, it will still using ur phone memory but very2 little.
For example; my phone without App2SD and i have nearly 60 apps installed : Available space in internal phone memory = 20-25MB only.
But with App2SD, avaiable space is 90-100MB.
