i dont think (as of the moment) we can buy just the unit of iPhone 4 from Vodafone Qatar. it comes with flexi 220 and saving 295 QR from iPhone 4 16GB for 2,850 QR and iPhone 4 32GB for 3,359 QR SRP (Standard Retail Price).

it's unlocked to use with any sim cards that you have. but it's not jailbroken and they don't jailbreak iPhones.
