Description

The T28 was the lightest and slimmest mobile phone at the time, with a weight of only 83 grams. [1]

Like many mobile phones of the time (1999) it had a fixed, stubby external antenna. It was probably best known as the first phone that used lithium polymer batteries. At one point, it was the best selling mobile phone in America.

In terms of market positioning, Ericsson designated this as a premium phone, as such it was priced substantially higher (often more than triple) the price of the T10 and T18 devices - their nearest cosmetic and functional competitors. It has a tiny LCD screen and a spring-loaded latch mechanism to release the 'flip.'

Models

Four different versions of the T28 were sold. T28z was compatible with GSM1900 for use in North America. T28s was compatible with GSM900/1800 for use in the rest of the world - this is by far the most common version. T28 World was compatible with GSM900/1900 for use worldwide on GSM900 and North America on GSM1900 (this was the second World phone Ericsson introduced, the first being the I888 which had the distinction of being the first commercially available GSM900/1900 phone). A special version, the T28sc was released in China with support for reading and entering Chinese characters.

The device came in three colours—very dark blue, lighter blue and sand. The sand version being the least common.

The device was listed as compatible with two batteries. A normal slim-line and an ultra-slim lower capacity battery. However the device was also battery-compatible with the later R320 and R520 series.

<span class="mw-page-title-main">Motorola StarTAC</span> Mobile phone

The Motorola StarTAC, first released on January 3, 1996, is often assumed to be the first ever clamshell (flip) mobile phone. Technically, however, NEC had been releasing flip phones on NTT Docomo's PDC Mova network long before 1996, namely the TZ-804 and TZ-1501, both respectively launched in 1991 and late 1994. Another early precursor of this form factor was the Grillo, which was designed in Italy by Richard Sapper and Marco Zanuso in 1965. The StarTAC is the successor of the MicroTAC, a semi-clamshell design first launched in 1989. Whereas the MicroTAC's flip folded down from below the keypad, the StarTAC folded up from above the display. In 2005, PC World named the StarTAC as the 6th Greatest Gadget of the Past 50 Years. The StarTAC was among the first mobile phones to gain widespread consumer adoption; approximately 60 million StarTACs were sold.

The new "BestPic" feature takes 9 full quality snapshots of a subject in quick succession, allowing the user to choose the best shots from them. On the entertainment front, the phones have a media player supporting MP3, AAC/AAC+/eAAC+ and WMA music files and 3GP/MPEG-4 video files. The phones also feature a RDS FM radio, and a Memory Stick Micro (M2) slot for expandable solid state memory. The K790/K800 models are also the first Sony Ericsson mobile phones to use ATI's Imageon 2192 graphics engine, which delivers a full 3D gaming graphics for Java and full support for its 3.2-megapixel camera.

The 8850 is considered to be an un-repairable phone, thus resulting in very few active handsets in the market. Today it remains a collector's item. It also came in gold. It was introduced as a successor of an earlier model, the chrome phone Nokia 8810.

The Motorola MicroTAC is a cellular phone first manufactured as an analog version in 1989. GSM-compatible and TDMA/Dual-Mode versions were introduced in 1994. The MicroTAC introduced a new "flip" design, where the "mouthpiece" folded over the keypad, although on later production the "mouthpiece" was actually located in the base of the phone, along with the ringer. This set the standard and became the model for modern flip phones today. Its predecessor was the much larger Motorola DynaTAC and it was succeeded by the Motorola StarTAC in 1996. "TAC" was an abbreviation of "Total Area Coverage" in all three models.
