wonder is anyone has experienced the same problem and maybe has a solution.
If I go intro address book, scroll to an entry, then select menu option "SMS name", sometime it brings up the SMS dialogue and sometime it doesn't. When it doesn't, nothing happens, the menu closes and I'm just back in the address book.
It seems to work OK with some address book entries but not with others. There is no pattern. Address book entries that previously allowed me to SMS sometimes stop working.
