phone not ringing on new sms...

[j3z3l]

does anyone else have a problem with thier phone not ringing on a new sms, it sometimes rings and sometimes doesn't.. i think it doesn't when it's asleep...

I already tried the registery hack to wake up on new sms and i don't think it works???

any help will be greatly appreciated... i get a lot of texts and most don't ring and i don't notice them til later on.... Sucks and stupid that this phone does this..
