Well, If you use a browser like Skyfire or Opera you can tap the screen twice fast and you can zoom in then tap twice quick again to zoom back out. If you use certain builds of Opera 9.5 browser, on the lower left corner you can click on the magnifying glass and a slider will come up and you can zoom in gradually by sliding the slider from left to right. As far as I know there is no "pinch" gesture on any browser for WinMo but the tap twice gesture works just fine.
