Gadgets on the go » People you know have spent small fortunes on shiny new smart phones such as the iPhone 3GS, a BlackBerry or the Droid. But the devices still don't have all the features they want. The battery runs out too quickly. They wish the phone offered turn-by-turn directions like a true GPS unit. A tripod would come in handy when they want to take a group photo on the phone for Facebook. All these holes can be filled by accessories that make for good gifts.

TomTom for iPhone Car Kit, $119.95

What it is » This kit from TomTom Inc. makes the iPhone easier to use for in-car navigation. The kit includes a mount and a car charger. In addition to this kit, your recipient would need a GPS application on the iPhone -- TomTom sells one for $100, with no monthly fees.

Pros » The TomTom mount is sturdy and grips the windshield tightly. It tilts forward and back, and rotates for viewing maps in landscape mode. The mount has a built-in GPS receiver to boost signals, a speaker for louder instructions and a microphone so you can take calls hands free. The mount also charges the iPhone.

Cons » There are cheaper GPS apps and third-party car kits on the market.

Mophie Juice Pack Air for the iPhone, $79.95

What it is » It's an iPhone case that just about doubles the life of the phone's battery as well. The phone charges through a connection port embedded in the case.

Pros » I like the battery indicator lights on the back of the case that tell you when you're about to run out of power. It has a standby mode, so you can use the Juice Pack battery only when needed. You can charge your iPhone and the battery case at the same time. It handles 500 full recharges.

Cons » The top of the case doesn't curve over the iPhone screen, making me worry that there's less protection if I drop my phone face down.

Where to buy » Online and various retail stores.

Gorillamobile tripod, $39.95 for iPhones, $29.95 for all other devices

Pros » Propping up your phone to take group photos or self portraits isn't the easiest of tasks. Gorillamobile by Joby aims to solve that with a 6.5-inch malleable tripod whose legs wrap around the trickiest of terrains.

The tripod attaches to the back of an iPhone case, which is included. For other phones, clips attach to the back of the device with suction cups or adhesive. The tripod hooks into the clip. Gorillamobile also can be used to prop up your phone so you can watch videos on it.

Cons » I'm not crazy about packing a tripod in my purse, even if it's only 6.5 inches long.

MoGo Talk, $129.95

Pros » In the category of "Why didn't they think of this before?" MoGo Talk solves the annoying problem of having to scrounge around in my purse for my Bluetooth earpiece device when someone calls. MoGo Talk's phone case (currently shipping for the iPhone but BlackBerry Curve and Javelin to come in the first quarter) has a Bluetooth device that fits snugly in the back -- so it's always attached to the phone. You can choose among different sizes of rubber ear tips for the most comfortable fit.

Cons » Like the Juice Pack Air, the phone case doesn't curve around the iPhone's screen so there's less protection for the front.

Where to buy » At Apple.com, Apple retail stores and MogoStore.com through year's end. Then it is due to hit retail stores.
