The usually locked iPhone 4 comes with a two year contract with the AT&T carrier ( in US) . That means you cannot choose the carrier of your own choice . Also you cannot switch between your contact numbers. But if you own a factory unlocked iPhone 4 , you are absolutely free from any such contracts and you can choose any carrier of your own choice. This enables you to use any local SIM card of your choice and thus save high roaming charges . You can opt for any supported carrier which suits you and use it in your phone rather than sticking to the same carrier for two years with no choice at all. You can switch your SIM cards and use nay number you wish to. Although unlocking your iPhone 4 still enables you to use your two year contract . But as you can see the benefits of an iPhone 4 factory unlocked. Much more cost efficient and user friendly. The freedom to use any GSM carrier makes it one of the most successful smartphone of the year.

I never buys an unlock phone because it is very expensive. What I also do is I buy a lock phone and have it iphone factory unlock at Jailbreakhome.com. That way, I can save more money than buying an unlock one.
