1. in order to make tweaks you will need a registry editor. there are 2 good ones i can think of off the top of my head. phm registry editor and total commander. do a search and you should find a cab for them. if not ill post one later tonight.

2. the theme im making will be easy to install. ill just put it in a .zip file and all you'll have to do is unzip it to your /windows folder.

3. most battery tweaks are spread out over the forum, the best way to find them is by searching. or alternatively you can load a custom rom which has all the tweaks included (see the diamond upgrade forum stickies to find out more about this)

as for what a .cab file is...basically you save the file onto your device, for example i save mine in "internal storage/cabs" (you can store them where ever you want). then after it is saved use the "file explorer" (its in the programs menu) to navigate to where you stored it. when you see the file just click on it and the .cab will do whatever it was designed to do. some .cab files install programs, some just make registery changes, some install files to your phone, etc. but they are mostly used for installing applications
