Several government agencies have started to gravitate away from RIM's BlackBerry smartphone for other alternatives, and the latest is the National Transportation Safety Board. According to AllThingsD, the agency has decided to ditch BlackBerry in favor of the iPhone 5 on Verizon Wireless because RIM's smartphones have "been failing both at inopportune times and at an unacceptable rate."

"The NTSB requires effective, reliable and stable communication capabilities to carry out its primary investigative mission and to ensure employee safety in remote locations," the NTSB said in a statement recently. It said it is not looking for competitive quotes, either, which means it's pretty much settled on the new decision. As AllThingsD notes, the Bureau of Alcohol, Tobacco, Firearms and explosives and the U.S. Immigration and Customers Enforcement Agency have also ditched BlackBerry.

RIM's certainly going to need to impress more than just consumers when it launches BlackBerry 10 in January. Enterprise and government customers have been huge moneymakers for the firm in the past, and it needs to continue to attract them.
