I don't know offhand, but:

man dd

might provide some information

EDIT: And welcome to Arch, or at least the forums

Re: help with dd command

dd if=/dev/sdb of=winmobile.img bs=512

...although this would be pretty tedious, I recommend a byte size of 1M or more instead.

Re: help with dd command

i believe the total size of the phones partition is 120mb.so change the bs= too 1024? i want it too be quick as possible,but not too the point of it missing files.as far as the command "of=winmobile.img",how does it know where too create the image file too?i dont have too tell it where too save the file to?thanks by the way.

Re: help with dd command

Sure, try it with bs=1024. If it gets too slow, increase it by twice as much to 2048 and so forth if necessary.

Using "of=winmobile.img" will put the image in your current working directory at time you enter the command. You can specify an absolute path instead if you want the file to be in a different location.
