Data transfer in the context of "IPhone (1st generation)"

The iPhone (also known as the iPhone 1st generation or iPhone 2G) is a smartphone developed and marketed by Apple as the first device in the iPhone lineup of smartphones. It features a Samsung S5L8900 SoC (90 nm), a 3.5 in multi-touch display, and a web browser (Safari). After years of rumors and speculation, it was officially announced on January 9, 2007, and was released in the United States on June 29, 2007.

Development of the iPhone began in 2005 and continued in secrecy until its public unveiling at Macworld 2007. The device broke with prevailing mobile phone designs by eliminating most physical hardware buttons, and relying on a finger-friendly touchscreen interface that did not need a stylus. The iPhone featured quad-band GSM cellular connectivity with GPRS and EDGE support for data transfer, and it used continuous internet access and onboard processing to support features unrelated to voice communication.

A satellite modem or satmodem is a modem used to establish data transfers using a communications satellite as a relay. A satellite modem's main function is to transform an input bitstream to a radio signal and vice versa.

There are some devices that include only a demodulator (and no modulator, thus only allowing data to be downloaded by satellite) that are also referred to as "satellite modems." These devices are used in satellite Internet access (in this case uploaded data is transferred through a conventional PSTN modem or an ADSL modem).
