Hello Everyone,

I got this 6310 v4.20, i want to upgrade it to latest firmware of this model or else can it be upgraded to 6310i ? Which latest firmware of 6310 & 6310i is available on the net ? and also i need to know how to flash this without loosing blutooth problem on the phone. I have DCT-4 Pro Flasher kit. So, I would request someone to guide me on how to proceed, coz this is first time i'am working on DCT-4

Also can someone tell me what features are there in 6310i ?
