Oh fresh....that looks complicated for a noob lime me...lol
Hmm. Well I dont want to push you into getting it. But just in case you want to know how to, ill show you.
You go to the link I provided and scroll down to the downloadable files.
Look for the link that has the word " corners OS" and download it.
Then once the files are downloaded you open the file/ folder.
Once you open the file you will see lots of APK files.. So since we have a MDPI phone you want the named " HGVA" ... There are two. One with a "3X" on it and one with a "5X" ..
You get to choose. The 3X means three desktop screens, and the 5X means five desktop screens.
You get the one you want and put it on your SD card.
Once you have it on your SD. Unplug your phone and browse your APPS.
Get your FILES MANAGER APP
Which you can get in the market, or if you have a CM7 ROM itll have it installed.
Then all you do is just browse to the place where you placed the file (HGVA etc.).
Touch or click on the file "HGVA etc" and then proceed to install.
VIOLA! Done. Now you can have that launcher.
