i really need to know this

1. what is phone unlocking? IMEI unlock??
2. what is debranding?

this is my confusion...please explain this to me and how this works...i dont want any wikipedia..bcoz i hate readiing long words..lol
so can u guys give your spontaneous answer?

Debranding - removing all icons,links,theme and other stuff ( T-mobile,O2,Vodafone ......) and puting original Sony Ericsson firmware

Unlocking- removing restriction for using SIM card other mobile operators

These days, most mobile phones come "locked" to a particular network - so for example if you bought a phone from Vodafone and later wanted to use an Orange sim card in it, it wouldn't work.

This can be annoying for several reasons. What if you have more than one mobile phone account with different networks but don't want to carry around two mobile phones? What if a friend's battery dies and they want to check their voicemail on your phone? What if you want to switch to a pay as you go or "sim only" tariff with a different provider and keep your current phone?

The only way to get around these problems is to unlock your mobile phone. It is completely legal, you own your mobile after all! The only reasons that the networks do it is to try to make sure you don't move to another network, but all it really does is stop you using your phone as you would like to!

ouhh...now i know..thx for the perspective!...for unlocking my country dont have that kinda problems...bcoz i dont even know it's exist or not..lol
