Hello guys,
I have this doubt, let me use an example:
Let's assume that I have 130MB free on the phone memory, then I install an app from the market. The phone memory drops to 120MB, then I move the app to the SD Card.. the phone memory returns to 126MB.. why this happens? What is this 4MB on the phone memory? Does the app left some "stuff" on the phone memory?
Thanks!

Yes, some files for the app are left on the internal memory.

To expound a little. The method you are using to move apps is the Froyo app2sd. This allows you to move portions of the app to the sdcard (but there still has to be some that resides on the internal memory, some apps you can move much more over, while others barely make a dent). Also, the dalvik cache for that app will stay on the internal memory and there is no built in way to change this. Also, when an app is moved to the sdcard using this method, you are unable to use the widgets that may be included with it, and any services that it starts won't run. This is due to the additional time it takes the sdcard to be prepared to be used once you boot up.
If you do need additional space, there are alternatives to Froyo's app2sd. The two most popular are DarkTremor's a2sd and S2E. The first is a file you have to flash everytime you flash your phone, while the second is an app that you get from the market. Both require you to partition your sdcard to create an ext partition (can be done in ROM Manager or the recovery), but partitioning your card will wipe it, so make sure you create a backup. These will allow you to move all apps to the ext partition along with the dalvik cache. This will leave you with most of your internal space free and you shouldn't notice much of a performance hit. Also, the ext partition is brought online much earlier in the boot process, so all of the apps functions (services and widgets) are able to be used without a problem.

I have a 1GB ext3 partition using rom manager (CWM v.5 ) I have only about 57 Mb free left in my internal memory. Free space software which I downloaded from market shows data space as 64% used.
Ext space used is 7%.
I have S2E installed. Am I to understand that I can now install apps worth approx 872 MB on my phone? ( that is the free space on ext3)
I apologise in advance if this is a really stupid question.
Many thanks
