I have gone through all threads regarding this error and NOTHING has helped. My phone app, contacts app, or messaging app wont open. I did back up my contacts but I cant find where at. i just updated to 2.2 using Samsung Kies Mini. I guess I also ROOTED my phone using SuperOneClick. I have rebooted a million times and i get the mnt/internal_sd/update.zip cant be found message. I really need to be able to use these features. I have read to clear the data off the contact storage section but I am not knowledgeable about any of this Im afraid to delete anything. PLEASE HELP ME!!!!! HAHA
