I have to opportunity to buy an unlocked iphone 4 (union wireless) to use an an ipod and a backup phone if something were to happen to my bionic. I was wondering if the sim card from my bionic would work in the iphone.
In short, no. Long version: Verizon sim cards are for 4g LTE access. IPhones do not currently support 4g. A sim card is not necessary for CDMA (3g data and Verizon voice).
You also may have trouble getting Verizon to activate a non-Verizon phone on your account even though it is unlocked. I have no idea on the last part though because I've never tried.
