Nokia E62 / E61

O.k... I haven't seen were anybody has updated the firmware of an e-62. has this been done yet? I noticed when I looked at installing some blackberry stuff that Nokia was asking which version of software my phone had. How do I upgrade to the newer version? Also, I have been try to encode video for play on the e-62 but am having no good success. Sometimes the videos will play but not smooth at all, very jerky! Does anyone have any recommendations as to what software I should use and what encoding options? Thanks!
