Old fashioned parents!!?

Okay im 15 years old making 16 in three months and my parents are too old fashioned...they dont dress old they are just sutck in their own time period and think teenagers are supoosed to be how they were when they teens. They cool people dont get moe wrong but they could really be uptight and aggravating. So they trust me for stupid stuff i did in my past and i have been doing everying thing to get their trust back but it never works. Also they dont allow me to have boyfriends bc they cant trust me and i cant even talk to them on my phone bf or not. and i just really want to know wat to do because i just got into a relationship but got my phone takin away bc my parents found out i was talking to boys. Im an honor roll student and i dnt get in trouble its just this boy problem that gets me in trouble bc how do you expect a 15 year old teenage girls not to talk to boys! can somebody please tell me what should i do bc i really like my bf but will not be able to talk to him without no phone!
