Are you looking for a factory unlocked iPhone 3G or the recently launched iPhone 3GS? Digital-Tek has put up a notice on their site that unlocked iPhone 3G and iPhone 3GS would be available from June 30. 

The devices would work with any GSM sim. There would be only two models available though, iPhone 3GS 32 GB (black and white) and iPhone 3G 16 GB (black and white).

However, be warned that the unlocked devices are going to cost you a fortune. For iPhone 3G 16GB, you’ll have to pay $450 and for the iPhone 3GS 32GB, the price is set at $699.
