Cell phone: There has been some concern of long term exposure to cell phone energy. However, overnite not of worry.

Relax: It takes a lot more than sleeping on a cell phone for a night to cause brain cancer; the distance from phone through pillow also decreases exposure.- another reason not to worry. The association of cell phone use and cancer is still pretty flimsy. Don't worry, be happy.

No risk: I wouldn't be concerned at all. The whole two-decades story of scared from cell phones and brain cancer showcases the crazy results that bad studies get from recall bias. Tell people that something causes cancer and they'll remember using it. One big study showed more cancer on the side opposite to where the folks held the cell phones. They don't produce the ionizing radiation that's dangerous.
