dont know but i've seen that 6610i is much slower than 6610(my dad used 6610 for 3 yrs)...may b coz of camera. and be reminded! only way to get the pics out of the phone is thru dku5(usb cable) or MMS...coz the infrared is only for phonebook entries. unlike 6020 where you can transfer images, amr/midi tones, softwares, contacts, videos(3gp) to other infrared devices or to pc.
