Boost Mobile, a prepaid US carrier powered by Sprint’s network, will be the latest carrier to add the iPhone to their lineup, according to Twitter user @evleaks. The phone is claimed to launch in Q3, and will make Boost the fourth prepaid carrier in the United States to carry Apple’s smartphone.

Sprint’s other prepaid holding, Virgin Mobile, has carried the iPhone since June of 2012 and recently launched a bizarrely awesome ad campaign to lure customers away from other networks. A competing prepaid carrier, Cricket, has also carried the iPhone since June. Straight Talk became the third big prepaid iPhone carrier in January of 2013.
