ok i upgrade my firmware to 2.1 unlocked iphone and pwaned it i can make calls browes the intenet and check weather and so so. but when i go on to you tube it tells me you tube unavaliable. what gives? i can't see to figure it out at all. i tried to change apn settings to epn.tmobile.com nothing happens. other people say that it ask for a screen name but mine just tells me that i don't have it avaliable so what can i do to correct this. cause everythings works except the you tube. before i did the 2.1 upgrade i had 2.0.2 and it still didn't work either. i did the unlocking with winpwn beta 2.5 and nothing. so i upgraded to 2.1 one and unlocked the phone with quickpwn. still no you tube can any one help me with this problem? thanks
