ROMS

What Is Rom ??

A custom ROM is a version of the Android operating system, with certain modifications. The open source nature of Android makes it easy for any developer to take the source code and tweak it the way they want. Customizations to the OS can range from trivial to very deep, depending on the developers’ intent and the amount of time they spend on it.
As for the reasons to install one, here’s my top list:

• I hate the bloatware that comes pre-installed with virtually every Android phone these days, eating up valuable internal memory and cluttering my app drawer for no good reason. Most custom ROMs will come without any unnecessary apps, leaving a clean, stock Android experience.
• Given their focus on speed and minimalism, custom ROMs usually feel snappier and run faster than stock ROMs. This is especially true of the excellent CyanogenMod.
• You can start playing around with the internals of your device – like overclocking the processor speed – if you are into that kind of stuff.
• Most importantly, for a lot of devices, custom ROMs are the only way to upgrade to the latest version of Android. If you are stuck with Froyo with a perennial ‘coming soon’ update like me, this is a way to tell the manufacturers and carriers to take a hike, and to take matters into your own hands.
