Our extended ROMs hold 10MB, if you got to start/settings/system/memory/storage card/extended_ROM then it will tell u how much free space u have there. They may not install 4+mb of crap like sprint does. But if not then u may have freespace and wanna customize/install some apps to ur extended.

Happy holidays!
