Mobile Carrier Web Page Reformatting Proxy Servers a Danger to Feature Phones? How About Skyfire & Opera Reformatting for Smartphones?

Windows Mobile’s awful web browser has forced me to consider alternative browsers on Windows Mobile phones for years. Skyfire’s browser became a lot more useable and useful after one of its updates last year. And, Opera Mini looks pretty good as of its update this year. However, I’ve always been concerned about the web proxys that both browsers use for their mobile page rendering magic. My rule has been to not use these browsers with websites that need an account name and password since I don’t know what their reformatting servers do with secure SSL connection (https).
