hi, may I know what does it mean by native A2SD? I s there any other kind of A2SD?
Let me try to explain this with my limited knowledge. I know nothing about Linux/SD ext etc until I bought my Nexus 3 months ago. By default all apps will be install in main memory. However Google had said the latest ver 2.2 will allow apps to be install onto SD card - this is native apps2sd. To be able to have apps install to card , the developer of the apps must built in this option for you to choose during installation. As of now many of the apps still do not have this option and the apps will be install in memory even if you are on ver 2.2 Android/Froyo.
Before ver 2.2 was released, many of the rom cooks customize the rom of previous ver 2.1 and even present ver 2.2 to allow you to "force install" onto the SD card - if you were to read into the details of the roms, usually 2 types - install directly to sd card ( ie on the FAT32 portion ) or install onto extended partitions , commonly called sd ext. Before you can use sd ext partiotion, you must partition your sd card first - there are several methods , the easiest is to use custom recovery. Using custom recovery you firs select the swap size, then the size of the extended partition, default is ext 2 - normally most people will use 512 MB upwards ; I use 1024 M. Once you have create this ext 2 , you can immediate upgrade it to ext 3 ( with journalling features). I notice most rom cooks will ask you to setup ext 3 , only a minority will be ext 4. These extended partitions you cannot view it in your computer as is hidden ; similarly in the phone using the file explorer , you cannot see it. Installing apps into the sd ext is the most popular method so far used by the various rom cooks.
for those rom that are customized to allow you to install directly on the SD card - you can view all the files/apps. In my various trials of the different roms, I find that apps install to sd ext is most reliable, can say is 100 % reliable. For roms where you force install on the sd card directly ( so called native apps2sd), depending on rom , sometimes some apps are not display when you put it out on the homescreen - what you see is just a blank image , but the link to the app still work. I believe this issue is only temporary until the apps are modified to allow installation directly to the card
I hope with this simplified explanation, you have a better idea
Any Linux experts, please correct me if I am wrong or best of all explain it further

got this from another forum:
SourceI do not own the desire but my Nexus is on the htc desire rom. Actually the settings to cahnge both wallpaer and lockscreen is in SETTINGS/PERSONALIZE. However on the Desire you see option for home wallpaper only. The lockscreen option is taken off - but HTC never update their manual which was based on previous earlier models, I think Hero
