How to change original (unchangeable?) ICCID/SIM card serial from an AVD

I need to have several running Android Virtual Devices, so have been trying to change the original ICCID/SIM card serial from an AVD and all the solutions I found oblige me to alter QEMU's code (see here: http://blog.codepainters.com/2010/11/20/android-emulator-patch-for-configurable-imei-imsi-and-sim-card-serial-number/) . I'm using: - Windows 7; - Java 1.7; - Android Studio 1.2.1.1; - Android SDK Tools 24.3.1. I'm emulating: - Android device with Gingerbread 2.3.3 (API 10). Does anyone got a solution? Thank you!
