For me this should be as standard on all mobiles! Looks like they are starting to do it in the US though:
Recently there has been a great deal of discussion about which platform would ultimately prove to be the dominant platform for which mobile applications are developed (including a strong case for mobile AJAX over at Open Garden’s )and while this doesn’t necessarily answer the question with any authority, the fact that a company as big as Verizon is showing such strong support for this mobile platform certainly has large implications for handset manufacturers and developers alike.”
