[HTC One X+] asimriz:
Hmmm well lets c. Instead of acting like a jackass & a **** & asking u to use google n such, I'll help u out with the basics if u've come from IOS (which I despise :P)...

1) ALL android apps (apps, games etc) extensions are .apk. To install them simply connect ur android phone via USB cable to ur PC. Now I'm assuming uve got an HOX+. Since no SD card is present, a window will pop up which is basically ur internal memory. Access it & make one folder called Download (that's what I do & I make sure that ANYTHING that is dloaded from the net on my phone goes into that one folder so that I always know where all my dloaded stuff is). The 2 main/best websites I use everyday for Android apps & games are:

http://www.ipmart-forum.com/forumdisplay.php?739-Android-OS-Zone

http://www.mobilephonetalk.com/forumdisplay.php?66-Android-Operating-System-Zone&

Register on these 2 forums. They have ALL the apps that u'll require. Yes ALL the apps :P Cracked too :P Just dload them, connect ur HOX+ to ur pc then copy the files onto the internal drive of ur HOX+. Then access the Download folder on ur HOX+ using a file manager. ASTRO File manager is the best !

2) If u don't like the HTC interface then u can install a launcher: ADW EX launcher, Launcher Pro Plus, APEX launcher are amongst the best. I used ADW when I started using android which was on my HTC Desire HD. However, that kinda became slow so I moved to Launcher Pro Plus which is perfect ! I'm still using it on my DHD which I rooted... If u root ur device then u can get rid of ALL bloatware thus making the ROM much lighter than stock. Anyway, I'm sure u get what I mean...

3) If u want a nicer clock with weather (this includes widgets) then use Beautiful Widgets. AMAZING app ! I just bought it, costs £3 I think maybe less but u get regular updates & the app is simply superb ! Worth every penny... I wud'n't suggest HD Widgets. Beautiful Widgets is just simple & light & u can dload clock & weather skins if u buy it...

4) When we do have a proper/stable way to root our HOX+ then I wud suggest flashing Android Revolution HD (ARHD by mike1986). It is IMHO the BEST custom rom out there for android phones.... I always found Cyanogen Mod to be unnecessarily complicated.... The best custom rom close to a stock rom is ARHD.... Mike1986 is a very dedicated dev & u get regular updates with his rom & lotsa other stuff as well... U'll see once u flash it...

5) What I usually do whenever I flash a custom rom is to remove the sense in that custom rom to make it lighter & MUCH faster. This is done using a No-Sense rom... Mike1986 provides ALL links to important flashable files in his thread so u needn't worry abt looking for such things....

Hmmm lets see what else ? Na I guess that's enuff of a crash course in Android :) I started using android in 2010 & went through MANY forums & learned a lot... XDA forums is the best forum for android device development etc... This is where I learned everything I know, not to mention my personal experiences here :D Hope I helped... Cheers man... p.s. to be very honest, it's more fun finding out stuff on ur own using search but it's always nice when someone lends u a helping hand...
