calendar and call history tab

[john80hotkey]

Has anyone come across a stable .cab of the sprint calendar and call history tab? I've ran across a few posts across the web including the ones on xda-developers. The cab installs and adds the tabs fine, but after a few swipes back and forth between the tabs tf3d locks up and freezes. it randomly chooses a tab to freeze on not always on the added tabs(calendar/call history) so I must remove tf3d plugin or reset the phone for it to function properly but it locks up again soon after, but if I remove the tabs and cab it returns to normal no crashes at all. I've done hard resets to no avail. Has anyone with a sprint tp tried one for some time and it actually worked? if so are there any tweaks or hacks I need to apply for it to work I really would like these. Thanks for any input
