I have a new Verizon 8830 - some sites I go to will allow me to log in, but then everything seems to go dead, meaning my cursor won't change to a hand over hyperlinks.
Blackberry Browser is very limited. You can try Opera Mini, but I wouldn't trust either one with super secret info... i.e. personal banking. Both browsers are proxy based surfers which means that data traverses a proxy server rather then website to device directly. Just FYI.
