Can any Wap 2.0 mobile phone access any Wap 1.2 content provider? As a Wap 1.2 content provider, should I change my Wap page(WML)? Does the mobile and/or the gateway provide such automatic transform function? Thanks!
"Any" might be a bit strong, but certainly all of the current and upcoming Nokia phones that support WAP 2.0 also support WAP 1.2 markup. There are also provisions in the WAP 2.0 spec for backward compatability to be handled in the server as well. So, rest assured, your WML content should be viable for some time. The biggest thing that will be changing soon is when phones switch from WAP stacks to TCP/IP stacks if you are running a secure site.
