That could be a problem.

This is a matter of debate. For the current generations
of mobile devices, bandwidth is at a premium as is display
size and flexibility.  Therefore, the optimzed protocols that
WAP gives you are a benefit to network health and performance.
Certainly, the tokenization of WML and XML are great
features even with 3G devices.
At the lowest level, the WDP/WTLS/WTP stack's value depends
on your target platform and scenario.

As the WAP forum moves forward on its goal of convergence
with true Internet Standards, this should be less of an issue.
