Now that the Android version of iFruit is out, it's possible to run iFruit using an Android virtual machine on Windows, Mac, or Linux.
- Download and install Genymotion, an Android virtual environment: https://cloud.genymo...chpad/download/
- Launch Genymotion. Press "Add" (you'll need a Genymotion account) and select Galaxy Nexus 4.2.2 - with Google Apps.
- Once this has installed, double click "Google Nexus - 4.2.2…" under "Your virtual devices". You'll be asked whether you want to configure "ADB connection". Select "No".
- Android will launch as a virtual machine on your computer. Insert your Google Account details (or create a new account) when prompted by Android.
- Go to Google Play, search for "iFruit" and install.
- Launch iFruit, insert your Rockstar Social Club account details when prompted.
I just did this (my phone is incompatible with iFruit), and am now playing around with iFruit.
Edit: GTASkunk suggests using Bluestacks, as an alternative method (Windows/Mac only).
It should be possible to do this without Genymotion, since this software simply streamlines installing a virtual machine manager (VirtualBox) and providing Android images. I haven't found an Android image I can successfully install iFruit on, other than the one provided by Genymotion.
