mobile phone jargon

With fresh innovations seemingly arriving every week, it can be hard to keep up with smartphone technology and new words that are coined to label them.

To make things a bit easier, we've compiled a list of common and not-so-common jargon along with simple explanations in layman's terms. So if you're muddled about megapixels or baffled by Bluetooth, we'll get you up to speed.

First-generation mobiles or mobile systems – these were the first-ever mobiles and provide the basis for all of today's smartphones.

2G
Second-generation mobiles or mobile systems – 2G mobiles supported data, fax and SMS mobile services. 2G handsets also offer limited data communications.
