what's the difference?

i remember reading from other thread about these stuffs:

what is a Nokia Symbian Phones ?

Nokia DCT 4 and DCT 3

so what's the difference between the DCT 4 and DCT3

when unlocking the nokia phone? also, wha't is CDMA specifically? what's the big difference about it?

i know some about 3G it's 3rd generation phone. but what is it actually? is it about the more speed or higher speed of data when sending via the internet and exchanging files? thanks for the replies in advance!

Symbian is the OS Nokia use on all their smart phones, Symbian also make OS's for other Companys, Its just the software on the phones.

These are just the 2 different unlocking algo's used, DCT3 is from the older phones (3210 etc) and DCT4 is from the newer phones (3200,3510i etc)

I'm not sure about this one now, someone correct me if im wrong, i think these phones dont have a sim card option the number is assigned to the phone itself! Im not sure, cause we dont have them here! But i think thats it.

Yeah 3G is faster connection from the phone its like mini-broadband, i have 3G on my phone and i get speeds of around 30-40kb/s! So it makes video calling and live video streaming possible with this generation of phones!

That help ya out?
