www.locateplus.com has simillar software, I know that they have it for blackberry...and again no, YOU can not get it.
You might note that BOTH Accurint and LocatePlus as restricted in certain states like California, New Jersey, Washington, Arizona (those I know off the top of my head) in DMV searches.....
In Arizona, (with the probable exception for law enforcement) you must go in person to the MVD (Motor Vehicle Department) to run plates....And YOU by the way, probably can not do that either! Some of here here might be able to though.
