No doubt, CitiGroup and Bank of America are two of the biggest banks in the USA. They already had a RIM designed corporate solution, with all the employees synched to a standalone server that managed their activities. Let’s say, emails, calendar invites, memos, notes, job postings and such sort of tasks were circulated among the bank employees through their Blackberries.

However, the senior officials are thinking of booting the RIM handset to introduce the iPhone as the new corporate solution. CitiGroup and Bank of America are in test phases, making the iPhone go through a series of operations.

For one reason or another, both banks haven’t been okay with the level of security that the Blackberry has. For now, whatever tests they’re carrying, they’re mostly linked to the iPhone’s security. Plus, these banks have their own Intranet based software that times all the iPhone or Blackberry based activities. Any 3rd party team, looking to access sensitive information has to crack the software.

Hence, the stronger the software is, there will be less chances of security protocol compromises. The test phase is constituent of over 1000 employees from both financial institutes. They’ll be using the iPhone for a few weeks to deduce a conclusion. There are also rumors about the iPad as the new corporate solution for the CitiGroup employees.

It looks like Blackberry guys will have to head back home for revisions. RIM had a tough time in UAE, India and Indonesia; they can’t afford to lose their clients like this. All the more, the iPhone based solution isn’t permanent. We already know the Android OS Honeycomb and Windows Phone 7 OS are spreading their tentacles. If they’re any better than the iPhone, the banks will be happy to rinse and repeat the entire process.
