SGS2 + CM9: Apex Launcher

Decided to give Apex Launcher a try, after months of sticking Trebuchet (default in CM9). Liking it so far. It's smooth, and offers plenty of neat features, such as "Lock desktop". I sometimes move stuff around unintentionally. Still yet to explore it fully. Also, this voting poll here helped me in choosing between Apex and Nova :P

From 3.8.17 to 3.9.16 (what happened to the versions in between?)

There's now the option to remove uninstalled apps from this list.

Are you really, really sure?

That's a lot of uninstalled applications..

SGS2 + CM9: HSPA+ Support

This feature was introduced in the 20120903 nightly (cm-9-20120903-NIGHTLY-galaxys2.zip). Since flashing 9.1.0, I'd only upgraded to 20120930. Now I know what "SystemUI: HSPA+ Support (android_frameworks_base)" means..

Notice the H+ beside the signal bar, still white in colour.

Now it's cyan.

HSPAP: 15 = H+ (Oh, I see....)
