infoWindow in google map not showing properly in an iPhone phonegap app - iphone

Question

I am showing custom marker with click event on it. It shows information when I clicked but the info window is not showing well. I used some css in it. I also need to customize it further. This map is shown in phonegap app in iPhone (iOS 5). Every other thing working find (including direction, GPS).
I have used google map js v3 API.
I got this output.
How to show correct infoWindow? And customize as my need.
here is the code
function setMap(myLat, myLng){
// Define Marker properties
var image = new google.maps.MarkerImage('images/pick.png',
new google.maps.Size(30, 40),
// The origin for this image is 0,0.
new google.maps.Point(0,0),
// The anchor for this image is the base of the flagpole at 9,36.
new google.maps.Point(9, 36)
);
var my_place = new google.maps.LatLng(myLat, myLng);
var myOptions = {
zoom:14,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false,
center: my_place
}
mer_map = new google.maps.Map(document.getElementById("mer_map_canvas"), myOptions);
mer_marker = new google.maps.Marker({
position: my_place,
map: mer_map,
clickable : true,
animation: google.maps.Animation.DROP,
icon: image
});
var contentString = '<div id="mer_map_info" style="border:3px solid red; color:#FFF; background-color:#000;"><p>this is just a test...</p></div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
google.maps.event.addListener(mer_marker, 'click', function(event) {
infowindow.open(mer_map,mer_marker);
});}

Give this a try. I had a similar problem with phonegap and google maps.
#map_canvas img {
max-width: none;
}
