I have searched the internet to no avail. I have a web client who wants to create a handheld-friendly version of his website. Anyone know of any script that can be used to identify that the user is on a pda?

The only methods I can find so far are identifying what browsers they are using, but there are no standard browsers as of this point, so there would have to be a lot of code for this. Is there a simpler way?

Any advice is appreciated.
