Flashing a 6610...

[frog]

ok i'm new here, and i've read some posts trying to gather some information...

can i flash my phone with just a data cable?

if so, can it be either usb or serial?

if i can with a data cable, then all do is download a program to flash it right?

ok, i so read a little more and found out some flasher kits on ebay but they only seem to be available in the UK (looking for the cheap ones). Now if i were to buy one of those, all i need is a program to flash it?
