Be sure to listen to Michael's conversation with Lester from the end of the previous mission called Marriage Counseling.
Head to Lester's house and Knock on the front door. Watch the cut scene.
After it's done head to a store called Suburban. Purchase a vest and some cargo shorts. The color combo doesn't really matter.
Now drive to the Lifeinvader office. Park out front and go to the rear entrance.
Follow a programmer into Lifeinvader. Sit down at the programmer's computer and close all the pop-ups on his computer. You can run the antivirus before closing all the pop ups, but it ill not properly run until all of the pop ups are closed. Move fast, as they reappear if you take too long.
Now enter the room off to the side. Michael will automatically sabotage the prototype, no need to do anything.
Leave the Lifeinvader office, get back into your car and return to Michael's house.
Go to the living room and change the channel until you see Lifeinvader's CEO Jay Norris on the screen. He will be talking about the cell phone prototype you just rigged.
Now pull up your own phone, open your contact list and find Jay Norris's name. Wait for Jay to bring out the phone, once he does, call him, and watch the fireworks.
After completing this mission you will unlock Rickie, the programmer. He will be available for future heists.
To get gold:
- Time - Complete the mission within 8 minutes and 30 seconds. Not too difficult, so long as you don't dawdle or wander around the Lifeinvader office.
- Popups Clear - Clear all pop ups within 32 seconds. This will probably require some practice. PC users will have an easier time using their mouse. (If there ever is a PC version that is).
