5. I honestly don't think you can change this. See, when you get a phone call if you are using an app the app will be minimized and still stay active in task manager. So when you end the call and it goes back to home, open task manager and select the app you were using and it will open back up.
6. Not sure if this is possible but I would check out the Touchflo3d or Manila 3d customizing threads to see if this has been done.
7. Well...you may have to reinstall those files and I'm not sure which files you need.
Maybe someone with your device can copy the appropriate files . Wow, you may have to hard reset to fix this.
That's the thing with SKTools. It is a great app but you have to be careful and not delete something too quickly . You can mess up things quickly if you aren't careful.
I hope you can figure it out. Maybe another TP2 user here can help.
Good Luck !!!
