have same problem
psychok7: were you able to fix this?
I've had the phone for a few months, and recently it started randomly shutting itself off. Sometimes it's frozen (only way is to remove then put back the battery), other times it just needs to be turned on. Battery itself has plenty of charge, so I don't think this is a power issue. Very strange and very frustrating.
Problem is I bought it in India (I live Europe), and can't take it back to the retailer...
