Now one can chat on International Calls in Local Call rates, by using a sticker.
This costs $35.
“It’s not hard to spend more on international roaming charges abroad than you did on the ticket there, but cloak your cell’s SIM card with a KnowRoaming sticker ($35) and you could be chatting andSnapchatting your heart out while only shelling out for local service. How? It recognizes when you’ve left your coverage area, and rather than switch to roaming, it seamlessly routes you through a local provider. They, in turn, get compensated for your talk and data usage via a prepaid account (which you manage via a dedicated app). And you won’t be need to use alias digits, either, since calls to your regular number are automatically forwarded.
Stingray can also be used with software called “FishHawk,” (PDF) ..
Cost: $68,479 for the original Stingray; $134,952 for Stingray II…
The Gossamer is a small portable device that can be used to secretly gather data on mobile phones operating in a target area. It sends out a covert signal that tricks phones into handing over their unique codes—such as the IMSI and TMSI—which can be used to identify users and home in on specific devices of interest. What makes it different from the Stingray? Not only is the Gossamer much smaller, but it can also be used to perform a denial-of-service attack on phone users, blocking targeted people from making or receiving calls, according tomarketing materials (PDF) published by a Brazilian reseller of the Harris equipment. The Gossamer has the appearance of a clunky-looking handheld transceiver. One photograph filed with the US Patent and Trademark Office shows it displaying an option for “mobile interrogation” on its small LCD screen, which sits above a telephone-style keypad.
First used: Trademark records show that a registration for the Gossamer was first filed in October 2001.

Some useful tips to charge and preserve the Mobile Phone charge,
Increase Time between Charges
Turn the phone off. This will probably be the most effective and simple way of conserving your battery’s power. Why? This will help conserve energy and also charge your phone. If you don’t plan on answering the phone while you’re sleeping or after business hours, just turn it off. Do the same if you are in an area with no reception (such as a subway or remote area, since constantly searching for service depletes the battery fairly quickly.) Some phones have an automatic power save feature, but it takes about 30 minutes with no service to kick in. By then, much battery power has been used. If you don’t need to receive or make calls but are using a smartphone as a PDA, disable the phone functionality (flight mode).
Stop searching for a signal. When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so. This is easily understood if you have ever forgotten to turn off your phone on a flight. The best way to ensure longer battery life is to make sure you have a great signal where you use your phone. If you don’t have a perfect signal, get a cell phone repeater which will amplify the signal to provide near perfect reception anywhere.
Follow the method of full charge and full discharge. Don’t put your phone on charging when there is the battery remaining it for another few hours unless it’s very important. Charge it when your battery is about to get totally discharged and when you put it for charging, let it get charged totally. OR Do the opposite – Some Articles  indicate that with Lithium batteries, doing shallow discharges and frequent charging prolongs battery life.
Switch the vibrate function off on your phone, using just the ring tone. The vibrate function uses additional battery power. Keep the ring tone volume as low as possible.
Turn off your phone’s back light. The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the back light in bright conditions and enable it in darker ones.
Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.
Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, “I think my battery’s dying,” and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.
Turn off Bluetooth. It will drain your battery very quickly.
Same goes for WIFI, GPS, and infrared capabilities, if your phone has these features built in. Keep them off except when you need them.
Turn the brightness of the display to the lowest setting possible.
Use GSM rather than 3G – Using your phone in 3G / Dual Mode will drain the battery quicker than if you just use GSM mode – have a look at your phones spec and you’ll see it will quote two different battery life times – normally 50% more for pure GSM use.
Take the phone out of the water as soon as possible. Ports for hands free kit, tiny hole for microphone, charging, usb cable connectivity and the plastic covers on cell phones even though tight can freely allow water to enter the phone in a just a few seconds of time. Grab your phone quickly, and turn it off immediately, as leaving it on can cause it to short circuit – if it has been in water, assume it is waterlogged whether it is still working or not.(wiki How)
