What is Firmware Flashing?
QUOTE(Wikipedia)
Flashing is the process of replacing a cell phone's firmware, usually to replace the original firmware with updated or custom firmware. Flashing is often performed to remove restrictions put on a phone by that phone's wireless carrier. While flashing is not illegal, it usually voids any warranty offered by the service provider.
Flashing is accomplished by connecting a phone to a computer using a data cable and copying new software from the computer onto the phone.

Flashing is changing the phone's internal software, also known as firmware update.
This can be done to upgrade to a newer version which has bugs fixed, modify the phone's features or modding (usually on S30 or S40 phones, add ring tones, change graphics, add features).
It is called "flashing" because the phone's operating system is not stored on a memory such a hard disk, they are stored in a chip which need direct programming (ROM), but with flashing possibility "flash memory" chip, that's mean "flashing".

What is branding/debranding and firmware customisation?
QUOTE(SE-NSE: thanks to iRonTech)
Customization is changing or replacing original content of the phone, like ringtones, wallpapers, icons, themes, that come with branded or unbranded phones. It also includes removing text message storage limit, mute camera shutter sound etc.
Branded Phones = Some network providers place their own ringtones, themes, icons, links etc within phone's software. (eg. vodafone/telenor, orange, t-mobile, rogers, cingular etc.) Debranding means removing all this content and restoring phone to it's original factory/generic condition. This will not damage phone in any way!
