if i understand you correctly, when you're composing a new sms, you're typing a name of a person in the "to: " field and aren't getting any results in the dropdown box. i would check your contacts and make sure they're all imported correctly. next, try sending an sms from the contacts application instead. just tap on the picture next to the contact's name and a list of icons should appear where you can select the messaging icon. see if that works better.
