This depends on whether you wish to install the full skin data including player pics or simply the basic data. As a general rule, we recommend having at least 200MB free when installing the basic data (the actual download size is a lot less though).
Please allow space for the full skin data including player pics depending on your device's screen resolution as follows:
- HVGA (480 x 320) - 320MB
- WVGA (800 x 480) - 380MB
- HD devices (640p or higher) - 500MB
