Griffin, the maker of Apple accessories, has come out with an antenna booster/case for your iPhone. I am typically leery of any “passive” antenna claims, this gadget doesn’t even plug into your iPhone… it is just built into the case. After watching Griffin’s nifty video, I think it may just work (for a 5db to 10db gain). The coolest thing I learned however, is how to get in to your iPhone’s “field test mode”… you gotta try this – dial the following *3001#12345#* and hit “send”. Tinker away.
Too bad it makes your iPhone look like a Treo, and our favorite case is still the Incase Slider.
Griffin claims the following:
- Boosts the built-in antenna of your iPhone
- Fewer dropped calls, cleaner signal
- Wider service areas
- Physical protection against bumps and scratches
