change timescape home

[demongrowl]

I bought my x10 on ebay, and lets just say it had its share of problems. I figured everything else out, including how to sideload a keyboard so i would have an input method, but I cannot figure out how to get a default android home screen. When I hit the home button, it always goes to timescape. is there a default one that us possibly missing from my phone, or do i need to download helix or ihome
