Rene from our friends at The iPhone Blog must be feeling his oats -- it's not enough that they talk about Mobile Safari is better than PocketIE (it is), he has to point out that even some of our alternatives aren't quite up to snuff. Case in point: Opera Mini. It's a great little browser (though it does require you use a Java Virtual Machine) that keeps most of the work of rendering the pages on Opera's proxy servers -- meaning you get the pages pre-rendered for your screen very quickly. All in all, good stuff.
Good stuff, but not necessarily secure stuff. Take a gander at Opera Mini's security page:
Is there any end-to-end security between my handset and — for example — paypal.com or my bank?
No. If you need full end-to-end encryption, you should use a full Web browser such as Opera Mobile.
Also notable for folks who might be tempted to access very sensitive info via Opera Mini: since it uses a proxy server, technically you're giving any passwords you use in Opera Mini to Opera. Of course they promise not to keep them or use them (and of course we trust them not to, Opera's good people). But if you're the paranoid type, Opera Mobile might be the better choice. Once Opera Mobile 9.5 hits, well, we'll be telling you to use that regardless.
