Samsung SCH-A670

i have a question about txts. when i have it on vibrate and i get a text it vibrates but then beeps later if i dont check it. is there any way to make it vibrate again after i dont check it? if that makes any sense

also the T9 word sucks i always have to change it halfway through to type a word it doesnt recognize. it doesnt recognize even simple words and sometimes it doesnt let me type any more letters for a word. is this just me or is there a way to fix it?
