Sony Ericsson Z520a


In the market for a no-nonsense flip phone that won't let you down? Consider the Sony Ericsson Z520a. It's a durable cell phone with its share of must-have extra features (camera, video, Bluetooth, and MP3 player). However, it lacks enough memory for...

Sony Ericsson W960i Review


Sony Ericsson, one of the most important handsets manufacturers, is also one of the fewest that managed to educate its fans and teach them how to choose their future mobile phones. From this point of view, things are much easier for the...

An interesting mix of business and music features enlarges W960i's target, widening its desirability. Excellent sound, high WiFi speed and 8GB storage space, as well as very fast USB data transfers speeds also rise its functionality. I should also...

Well, there is always room for better, so HSDPA and EDGE technologies should've been included. There's also the slow working interface which could have definitely been improved if a better CPU had been included

Sony Ericsson Z520a Review


Good form factor and keypad

Flip up cover not easy to open, Some have reported spotty reception

Feature-rich for a free phone and a great form factor, but some drawbacks on quality may not satisfy the serious user.

Sony Ericsson Z520a Review


Setting their sights on the image conscious consumer, the new Z520a by Sony Ericsson builds upon the Z500a released last year. More of a fun phone than a business device, the Z520a featuring Style-Up exchangeable front and back covers, allowing users...

However, possibly the largest drawback is the limited memory and mediocre LCDs. Able to play MP3s through the Media Player, unfortunately limited to 16 MB of internal storage and no expandable memory card slot, consumers can put all of a laughable 4-5...

Sony Ericsson Z520i Cell Phone Review


If a cool clamshell with every possible customising option is what you want, the Z520i is your phone. You can change the front and back covers, and have any combination of ringtones, images and light effects play when a call comes in. And you can have...

Sony Ericsson W980i


The Sony Ericsson w980/w980i Walkman phone is designed to allow you to listen to music as it should be heard. Clear stereo enables the music to sound like the original recording. With 8GB internal memory, the W980i stores up to 8000 songs (eAAC+ format).

As said, the W980 is in my opinion a very good mobile phone but withsome disadvantages. I wouldn’t doubt for a second that it's going to bea very popular music phone, though.

Sony Ericsson W950i


Sony Ericsson W950 is based on the new Symbian v9.1 and UIQ 3.0 platform, ultra-stylish UMTS WALKMAN phone. Built-in 4GB storage plus high performance entertainment suite with touch screen.

The call quality was clear, I didn't notice any distortions in the sound, I didn't get any dropped calls except on the bus, but I suspect it was a coverage gap on the network's behalf, since Cingular uses a mix of both 850Mhz and 1900Mhz depending on...
