Why do you want to jailbreak an iPhone? You won't get all the functionality it provides once you jailbreak it. Vodafone is selling the iPhone unlocked officially from Apple. You can use it with any mobile service provider like Qtel. I personally bought it from them, the 3GS 32GB. I am now overseas doing my degree and I am using it with the service provider here. It is working perfectly. I think you should sell your iPhone and buy one from Vodafone. Much easier and safer.
