Cross Browser Issues Within Buddypres Social Theme

I just installed the Social theme today after my site got screwed up over a faulty plugin.... Everything within my site works smoothly within the new theme (buddypress social) for the most part.. however i noticed that the color schemes were not properly displaying within the internet explorer 9 browser as they were showing flawlessly inside of the google chrome browser....a minor problem, so i decided to check it out on my mobile phone(s) first up, i checked it on the Motorola Droid Razr... the site colors showed up perfectly however the navigaion menus were non existant <not the main navigation links home, members, etc, but the ones that navigate the personal links to profile, activity, friends, followers, etc> those didnt show up at all... so i went over to my blackberry... it seems that on my mobiles, all of the links in the header area are nonexistent .. how do i fix this? any help would be appreciated...
