I deleted the vad files, pre loaded media, etc.. to save space. I also deleted the BB Dimension Today and Dimension Icon theme as I never use them. I have a couple custom made themes I use so I loaded those on. My question is since I never use the Zen theme can I also delete that or no? Someone told me that if I delete the Zen theme I would have all kinds of issues because the BlackBerry needs that theme to run. Is that true at all or no? Currently after this OS update theme wise I have: Dimension L, Dimension Zen and two custom themes. I want to delete the Zen one also but thought I'd get feedback from the BB Experts here.
