One of the beauties of being able to tinker with our devices is how it allows us to have flexibility. Most countries around the world have several choices when it comes to mobile service, and among them you have the ones that will welcome you with open arms and that ones that simply do not want to let you go. How do the latter accomplish this? They lock the phones to their networks so that they cannot be used on others. Because of this, ever since XDA has been XDA, we have striven to do away with this ridiculous concept that is the carrier lock. The reason is simple, you pay good money for your device, you should be able to use it wherever and with whomever you see fit. XDA Forum Member fatclue had this idea as well and after searching far and wide he came across a guide, which he posted on xda-develoepers about how to get the Samsung Focus onto the no-contract carrier Straight Talk in the US.
The procedure is very well explained and goes into very deep detail regarding what tools are needed to get the device working on the network. The only real block on this is the fact that the procedure will require the device to be Interop-unlocked due to the low level tools that are required for this operation, such as WP Root Tools as well as access to the registry. The Focus is a device that can be unlocked by following this guide by XDA Recognized Developer Heathcliff74.
So, if you feel like getting out of an expensive contract and still be able to use your beloved Focus while saving some money in the process, please follow the steps in the guide, and leave some feedback for the dev as well.

Okay, I’m going to try to list the steps to get internet sharing and MMS working with Straight Talk, Please bear with me since I’ve only been playing with WP7 for a couple of weeks, I’m a webOS refugee and I seek asylum within the Windows world.
