Over the weekend, I was suddenly no longer able to edit any of my existing contact information or add new contacts. I updated my phone, and that did nothing. Any help would be appreciated.
If you have updated any of the IM apps (Yahoo Messenger, MSN Messenger, Gtalk) delete it and restart your phone. There is an issue with the latest updates.
Nope, I don't have any of that on my phone. Perhaps I should clarify - it's the contacts in my "phone book" that i can't edit or add to.
