My friend got his Samsung SGH D500 today and he asked me to make a post here (ya, he doesen't have internet but has a D500, weird ) and ask in his name what the fastest data transfer would be for his D500 ?

An IrDA (Infrared) adapter, a Bluetooth adapter or a Data Cable ?

Thanks in advance.

edit: I see its a phone, a data cable would probably still be fastest

No, from D500 (phone) to PC

d500 is a phone

i would say data cable, but really how much data can one transfer to a phone ?

Probably Bluetooth and Data Cable will be tied.

Not only to the phone, but also from the phone (the D500 has 96 MB of internal memory)

Edit:
btw, he says he's got USB 2.0

like I said in my edited post, data cable will be fastest

Actually it depends on the quality of the cable you buy and even then bluetooth is faster than most cables.

I have a DC11 cable for my k700i and have used a bluetooth adapter with the phone as well and the bluetooth adapter was consideribly faster.

I don't have bluetooth. I just use the cable for my Nokia. But I've heard bluetooth is faster.

Bluetooth 1.1 and even 1.2 are way slower than USB. Hence the need for a new standard, due out soon 'Wireless USB'

Thanks for your replys.But he bought a Bluetooth USB adapter today.I think it's the best solution.He and his brother have both the D500 and it's easy for them to send/recive data from/to the the PC that way (they both use 1 PC).

i just bought a bluetooth dongle for my pc... i can transfer files to my x50 at about 40KB/s ... not bad but nothing great... i still think connecting the pda straight to the base is better... (i know we're talking about a cell phone here) but i would say data cable would be the best.
