AT&T Unlock iPhone 4 – Things you should know
As you should already know, Apple makes its first iPhone releases in US and the most popular carrier there is AT&T. The price to purchase an unlocked iPhone 4 from Apple is extremely high, so they sell them with a 2-year contract in a lower price. The problem having a locked iPhone to AT&T (or any other carrier) is that you are unable to use it with a different SIM card, and if you travel abroad you will have use the roaming services (which are extremely expensive).

AT&T Unlock iPhone 4 – What method to use?
Until now, there are three methods available to unlock AT&T carrier from your iPhone 4, the software, the hardware and the official unlocking method.
The FREE solution is to go for a software unlock, but for iPhone 4 this can only happen if you have the 01.59.00 baseband version. The software unlock uses an iOS hack, that tricks your carrier and makes it possible to use ANY SIM-Card you want to your iPhone.
On the other hand, the hardware unlock is not FREE (Around $50), but the feedback of people that used it is not very positive. Many people reported that they experienced call drops, weak signals and a few times no unlocking at all. You need to be very careful if you are going to choose the hardware unlocking method and do a very good research!
