Can anyone explain to me what WAP vs xhtml is all about?
 

Android and iphone uses xhtml right?

So what the hell is wap? What kind of browser wap is? How can anyone pay for crappy mobile pics?

for example I saw:

iPhone / iPod, Android, BlackBerry (newer devices), Opera Mobile (newer devices), NetFront Browser (newer devices), Partially Web-Capable Devices, WML-Only Devices, iPad in advidi.com

okay it says iPad, then it says WML only devices.

I thought iPad uses xhtml?

Wireless Application Protocol

You're asking several different questions here.

As mentioned in the post above WAP is the wireless protocol.

WML is the wireless markup language which precedes the use of XML and XHTML - now that mobile devices have more powerful processors, XHTML is being used more often.

It's pretty ancient technology, nothing to worry about :)
