Hi, I bought my n96 last September in Singapore. This few months I seem to be experiencing the same problem as u. My phone will restart once I receive new sms. And recently it went much worser that it freeze once it receive new sms, then i have to take out the batt and i then when i put it back it don startup immediately, i have to wait about 30 min for it to startup, sometime it even took whole day to startup. Really giving me headache nowadays.

Don mind if u can share with me how did u overcome ur prob. I will be really grateful to u. T
