The BlackBerry 8820 also supports UMA VOIP (Voice Over IP)-so there’s the potential for low-cost internet based calls, and also many corporates are rolling out VOIP already wired so this is an interesting migration path for users “in the office”.

Identical in appearance to the BlackBerry 8800 and black variant of the 8830, the RIM BlackBerry 8820 takes the 8800 configuration and adds WiFi capabilities.

The memory slot on the BlackBerry 8820 supports microSD cards (up to 2GB) and also microSDHC (high capacity) cards which can theoretically hold up to 32GB.

The two main improvements are the disk capacity - the Samsung i310 has an 8GB internal drive (the i300 has 3Gb and the i300x 4GB), and a long-overdue upgrade to Windows Mobile 5.0 system ‘exploitation. The camera has also been upgraded to 2 megapixels of 1.3 megapixels. The i310 now supports USB 2.0 for high-speed data transfers.

Essentially, the AMU is a second generation wireless VOIP based protocol that allows users to easily switch from a standard and a call cell based WiFi. Of course, you will need a compatible WiFi hotspot which you then to configure, so some assembly will be required with the P200.

The Samsung P200 is a conventional phone looking slip on the surface, but below it, in fact, a device capable of WiFi UMA / VOIP (Unlicensed Mobile Access / Voice Over IP) telephone.

Samsung say that after the launch of the P200 in Italy, then it should be available in other European countries during the second half of 2006.

The main feature of the sale SGH-U100 is its thinness. In many other respects, the U100 is somewhat compromised. For example, there is no expandable memory and the overall layout and design is somewhat a misnomer. It is interesting to note that although the SGH-U100 is a very thin phone is a bit width and height to 106 x 50mm. In other words, Samsung has achieved this impressive feat crush slimunisation by telephone shortly.

Nitpicking aside, the SGH-U100 is sufficiently capable phone for most people, and its ultra-slim design should give him enough “wow” factor. Samsung say that the U100 is expected to be available during the first quarter of 2007.

Samsung U700 features a 2.2 “240×320 pixels, a 3-megapixel camera with autofocus and a second appeal video camera, tri-band GSM, GPRS, EDGE, UMTS and HSDPA data, as well as Bluetooth and memory expandable microSD.

In terms of design, the U700 follows a very traditional route with Samsung in one case a little brighter. The design retailer has not really lift as much, but then really SGH-U700 strengths lie elsewhere.

Another member of Samsung’s Ultra Edition II range, the SGH-U700 is a bright and very thin slider with 3G HSDPA support.

The SGH-F200 of the screen is a bit 128 x 220 pixels in color 262000 panel. Internal memory is just 5 MB, but the standard package includes a microSD card of 512 MB, and the Samsung F200 can take up to 2 GB of RAM expansion. The SGH-F200 also supports Bluetooth stereo, and a stereo cable connection.

Although the F200 Samsung is very similar to that of an MP3 player, it is also a call. It supports tri-band 900/1800/1900 MHz GSM and GPRS.
