[N6255]

I have found some problem with this new CDMA Nokia 6255 phone, with base on Java OS.

This phone extreme good but some bug on new release.
1. Set short mp3 song (less then 10sec file) as ringtone, phone will restart if you have a miss called.
2. Bluetooth not compatible with bluetooth Sony Ericsson HBH-300, HBH-602, HBH-660, once press the bluetooth button and speak for dial person, and suddenly voice routed to handset.
3. New N6255 can't enter "Caller Groups" handset must "Restore factory setting" once, then "Caller Groups" working fine.

Please someone can answer this matter?

Thank you
