Everytime I go to my bank and try to log in and tap on log in, it just stays the same it doesn't log in!

So I called sprint and sprint said the Mogul doesn't support for login in to Bank Account!

Does anyone know how to work around this issue! I used to own the Palm Centro and I was able to log in! I use my phone on the go a lot and would be happy if I would be able to use my phone again to log in to my account! Any answers or tips would be most appreciated! Thanks!=D>
