i just bought this phone from a friend and i was wondering if tmobile will charge me to use the internet browser and youtube? i never had internet on my old phone nor ordered the hotspot stuff but now that i have the g1, i inserted my sim card and i can go on it. but yeah i just want to know if i will be billed later on for using it. lmk thanks! cause i dont want my bill to be like 300+

yes they will charge you
