You know how normally when you go to type an email to someone and you start typing there name in the TO: section Blackberry brings up all names in your address book with the letters you type to make it easier. Mine has stopped doing that. Now I have to manually type in email addresses. Now the thing is if I remove the battery from my device then reinsert it and restart, the feature comes back to working fine, then stops again in a couple days. Am I doing something wrong to make this happen? I thought it was an automatic feature. I'm scared my unit is defective or that I am doing something wrong. Please help!
