there are a lot of different versions of the opera browser out there, and not all of them work well under the titan(due to the titan low memory?). the one that work best for me is the opera browser from the samsung ominia build 1957 (now updated to 2520). however, this version of the opera browser has the annoying transparent windows overview. the folks at xda developers have figured it out how to removed the windows over by removing 2 png files from the skin file. well to put the long story short, i have compiled a new cab with the fix and you guys can get it here:

the cab also include these following hack: ie7 identifier, opera as default removal, and the opera diamond skin. install the cab into your device memory.
