Tuesday's Tech Tip: Cell phone tricks

Here are some cell phone tricks for today's tech tip:

1. Can't remember where you parked? Take a picture with your cell phone's camera. Most big parking lots and garages are labeled (Row B, Level 4 Orange and so on). Take a picture of that sign with your phone and you'll have a reference for when you come out of the mall.

2. Put the phone number of a reputable local locksmith on your phone. That way when you you find yourself locked out of your car or home, you'll have someone to call (yeah, yeah, assuming you have your phone on you).

3. Use SorryGottaGo.com to end annoying phone calls. You pick a section and then click on a sound effect to play in the background. For example, the At Home section has a sound for "Oh it's the contractor" and "The hot water is boiling over." I find it easier to say "I'm sorry I have to go," but some people need a little extra help.
