yes, you can buy micro sim from Q-tel or you can just change/convert your existing simcard to microsim for only 100QR...this way you can still use your same mobile numbers... i did it when i bought my iphone 4... actually i purchased it from vodaphone shop with free microsim but i love my old qtel sim so I went to the nearest Qtel office to change it to microsim without changing the numbers...visit the nearest Qtel office in your area.. your iphone will not work without microsimcard... good luck mate..
