Fans of mobile banking are discovering harsh surprises after updating their Atrix 4G to v4.1.83. Amongst the numerous improvements in this release (including the widely touted HSUPA fix), Motorola added new SSL certificates to the mix. While such a change would normally be inconsequential, many banking apps have stopped functioning with the new certificates in place -- a rude shock for anyone needing to deposit a paycheck. So far, Moto confirms that American Express, Bank of America, Chase and Discover are affected -- while Wells Fargo and Citibank's apps run just fine. Motorola plans to issue a workaround for affected users, but currently suggests that everyone access their financial institution through Android's web browser. Maybe it's just us, but this sounds like a fine opportunity to take the new Firefox 4 for a spin.
