[rhannahs19]

well my phone was fine... then i flashed with nex's iphone rom and immetidetely after i recieved a text or a phone call my phone would go into standby mode and id have to press the power button to turn it back on. for example, i will get a phone call and my phone will vibrate once, go into standby and then ill have to press the power button to turn it back on and answer the call.. i have since flashed to ppc kitchen, but i am still having the problem... does anyone know what might be causing this? thanks a lot guys
