My iPhone 3G was originally from US but I would like to use it in other countries, Can I use your simTray to unlock it?

Yes!

Which firmware do you support?

We support all firmware that are currently jailbroken. Furture firmware which can be jailbroken are very likely to be supported with no extra effort too!

Does your product work with the iPhone 3G?

Our unlocking tray works with iPhone 3G.

What is the difference between jailbreak and unlock?

When an iPhone is first taken out of box, it is not activated. The jailbreak process activates your iPhone as well as makes your iPhone ready for 3rd party applications.

Unlock is the process to get your iPhone to accept carriers (SIM cards) that your iPhone did not accept originally. This is what we do on top of jailbreak.

Do you sell jailbreak service or solution?

No. Jailbreak solutions are freely available over the internet. We do not sell either jailbreak service or solution.  We also do not provide technical support for the jailbreak process as you should have a jailbroken phone if you are purchasing our solution.  If you do not feel comfortable jailbreaking your phone, we do have pre-jailbroken iPhones available for purchase.
