I HAVE A PROBLEM MY CELL PHONE SHUT OFF BY IT SELF I DONT KNOW WHAT HAPPEN WHAT CAN I DO MY FRIEND TOLDS ME S THE SOFTWARE BUT I DONT KNOW WHERE CAN I GET IT
i dont this is the battery cause this cell phone works with nextel and boost and when i'd put the bostt sim card was sorking great but when i want to use with nextel the cell phone shut off byt itself

idk my bros nextel does that... check the battery, it turns off by itself if its low.. charge it for a while then try to turn it back on
