This one WORKS fine with all functions of the phone, smooth and fast 3G data connection.. just like a factory unlocked one. Most of the DIY unlock solutions for the 3G iPhone come with data connection problems. In this case, the whole thing has been programmed to this specific model - (it is still on 2.0 original firmware for u guys keepin' an eye on iphone dev team). If you're unsure, please check the pictures - my name and ebay uk is on the screen along with 3 UK network logo and 3G for data transfer. This solution does not affect the warranty at all. If u need help, I can install your card myself in 3 seconds if u do cash on collection. All questions are more than welcome
