There are many threads all over CB about this. RIM is aware of the problem and is trying to fix it. The only recommended fix I have seen is to delete .35, wipe your phone and reinstall the OS and then install App World .33.
what i dont get u is wat u mean wipe your phone and reinstall the OS and then install App world .33???
i've got the same issue. from .33 to .35 and poof...gone. if anyone figured out the solution, let me know. til then, i guess i'll try to redownload .33.
