copy the apps (stock,weather,clock,calc,voice,compass) from e.g iphone they are all in /applications folder simply just copied from iphone to ipad to same
/applications folder ensure permissons is 0755 or 0777
apps should work fine but possibly get a white icon.
ifso in the folder for each application there is a file called firstname.lastname@example.org
copy this onto you pc/mac
rename it to icon.png then copy it back (overwriting existing file (if neccessary) )
also ensure permisson is 0755 or 0777 and respring and you white icon will revert to normal
as of yet i dont think getting weather or stock in notifications
