Apple iPhone 4 comes with a MicroSIM option which is going to need the cutting of your normal SIM card into a smaller size. Even if you convert your normal SIM into a small sized one, the iPhone does not support a Dual SIM Card which is the reason its recommended to go for a Dual SIM Card Adapter which is going to make two carrier networks to run on the same device. We had earlier suggested a similar option to get Dual Sim Card Adapter for iPhone 3G / 3Gs.
The Adapter costs US$9.90 available at Deal Extreme with a option of enjoying dual carriers while you are in roaming between different countries or states. Do make a note that the price includes free shipping all over the world and can enable you to access two SIM Cards at the same time.
Easily to switch 2 SIM cards without turning off the phone; No need to cut your SIM card; No data loss when switching 2 numbers or turning on / off the phone; User friendly option menu will embed into your phone menu system; Very simple operation, easy plug and play.
