So I am a die hard Nokia fan, but their OS is just so washed out and boring. Even their MeeGo software looks boring so I see that the pretty big up and coming OS is Android. So i am considering getting the Dell Streak, but i have an unlocked Nokia N97 with a 10 dollar a month "stupid phone" unlimited data plan. So my question for everyone is if i buy this phone and pop in my current AT&T sim, will AT&T realize and make me switch my data plan???

PS- If anyone has the Streak can you tell me your opinion on it. Like does it actually look like a bomb in your hand when you walk down the street or do people say "hey what type of phone is that?" you know info like that. Thanks.
