guys, i need your help
i'm so stupid, i locked my phone by playing with lock patterns and can't unlock it now. i cannot login with my gmail account (i configured it on the phone) because i disabled apn and don't have wi-fi enabled. i need to do a hard reset, do you know how? i'd be so grateful for a solution
cheers

edit
solved :) turn off the phone, press and hold volume -, call and end buttons, when a screen with a triangle displays, press the menu key
