A flip phone from BlackBerry? Research in Motion surprises us again with another innovation – the BlackBerry Pearl Flip 8220. It has many new things: flip design, Instant Messaging software, bigger Suretype Keyboard and more…but are they enough for the BlackBerry Pearl Flip 8220 to eat into the flip phone markets? Let’s find out now.

The package is not very impressive, only the phone, battery, charger, handsfree, data cable and a pile of user’s guide are included. Since the phone is a fingerprint-magnetic beauty, I suppose RIM would at least include a cloth (or a case!).

As you can see, the front cover is dominated by the huge 1.6” external screen, which can display a digital clock (as shown) or new SMS.

When the BlackBerry Pearl Flip 8220 is flipped open, it is very long – which is one of the advantages of having a flip phone. The speaker is close to the ear while the microphone sits next to the lips, the design guarantees that you can hear and be heard clearly.

The trackball is horrible. The erratic response gives the feeling that the technology is still in its embryonic form. I had to be very careful with my thumb because rolling it too hard causes it to recognize 2 inputs. When I applied insufficient force, the trackball would physically roll, but the input would not be recognized. This is not to say that the trackball is unusable, you just have to be very careful with it – not a good thing if you are in a hurry.

Many long-term BlackBerry users have complained about the SureType keyboard, which groups 2 letters in one key as opposed to the 1-letter-1-key physical QWERTY keyboard found on other BlackBerries. I do not think that these complaints are very well justified since we are looking at a 50mm wide model, which is terribly deficient of space! The SureType keyboard is soft with a deep enough drive, predictive input works well and the only possible complaint is the slight delay before the predicted word menu show up.

A standard 3.5mm earphone jack! Obviously RIM understands the pain of carrying and installing an adapter for listening to 5 minutes of music. Strangely enough, the earphone jack and the data port lack a protective cover.

microSD can be removed without turning off the phone – good for swapping the card containing the next Lord of the Rings movie (secretly in a meeting)

The flash and message indicator sit next to the 2MP camera. The camera is far from spectacular with faded colors and soft sharpness.

The OS in the BlackBerry Pearl Flip 8220 may look slightly different from the ones you have seen before. This is partly due to the orientation of the screen (240 x 320 versus 320 x 240 on other BlackBerry devices) and partly due to the new features added. The menu is nicely organized and you can access most of the features without looking at the manual. For instance, “Manage Connections” allows you to handle GSM and Wi-Fi settings in one stop.

The BlackBerry Pearl Flip 8220 could have become the best flip phones today with its gorgeous design, SureType keyboard and the powerful business software suite but for the following glitches: 1) poor Trackball 2) mediocre camera 3) lack of 3G support.

How do GPRS, EDGE, UMTS, HSDPA, Wi-Fi, WiMax offer mobility to your internet service and work with speed?


Thanks to the rapid development of technology, mobile phones nowadays can do so much more than merely cellular communication. They have become smarter, not only name-wise, but also application-wise. Incorporating wireless data access technology, mobile phone has brought communications to another level -- offering mobility to the formerly fixed internet service. Web browsing, online video streaming, emailing and instant messaging previously monopolized by computers are now penetrated by third-generation mobile phones.

The wireless data standards are the keys to the world of World Wide Web. You may want to be familiar with the following terminology as the first step of get-online-with-your-mobile-phone knowhow.

1. GPRS
Phones with GPRS (General Packet Radio Service) might also be known to you as 2.5G. It delivers data rates up to 114 kbit/s theoretically, yet its typical rate is usually around 56kbit/s. Video conferences and interaction with multimedia websites are for the first time made possible, but often with frequent lagging. The a bit dated technology allows you to download some ringtones and games, some pieces of news on GPRS connection, but it will not be the choice for those with heavy internet consumption.

2. EDGE
EDGE (Enhanced Data Rates for GSM Evolution) reaches an effective data rates to around 180kbit/s, enabling transfer of multimedia and the delivery of some broadband application. It is defined by ITU as 3G technology, but is most commonly described as 2.75G.

3. UMTS
UMTS (Universal Mobile Telecommunications System) is what we usually refer to as 3G technology. It improves the data transfer rate to an effective rate of 384kbit/s. (Yes, the 2 Mbit/s is again, theoretical). It is fast enough for a smooth video streaming experience. However, some countries like the US and Japan who use a different banding, are not the beneficiaries of 3G technology. UMTS handsets though can still be operated since they usually can switch themselves back to previous GSM modes when UMTS connection is not available.

4. HSDPA
HSDPA (High Speed Downlink Packet Access) generally known as 3.75G technology, provides a speed of 400 to 700 kbit/s in usual practice. It is currently the most upgraded data transfer standard launched in the commercial market. (It is the beginning and you know how fast things are changing in the technology world!) Most of the latest models of Smartphone nowadays are heralded to have accelerated by HSDPA to allow a wider collections of media downloading and higher-speed web surfing.

Phones with up to HSDPA connection: Samsung M7500 Emporio Armani, Blackberry Storm 9530

5. Wi-Fi
Phones that support Wi-Fi allow internet access on a data speeds between 3 to 20 Mbit/s depending on the network attached. Places with Wi-Fi coverage are also called hotspots. If the café, restaurants, airports, libraries in your cities are hotspots, you can get online with your Wi-Fi compatible phones.

6. WiMax
WiMax is short for Worldwide Interoperability for Microwave Access. It’s a hopeful candidate along with LTE to achieve the 4G standard of 100 Mbit/s mobile and 1 Gbit/s fixed-nomadic bandwidth set by ITU. HTC has announced in November 2008 the first WiMax/GSM phone whose name HTC MAX 4G and it is expected to be launched in November 2009. It seems that to 4G destination is only at a distance!

If you want to access the internet with your mobile phones, you may go to the connectivity menu to see if your phones are equipped with the data transfer technology above. If they do, you will need to subscribe for a plan from one of your mobile phone service carriers to get your phone hooked to the net. Usually, the icon “G” or “Wi-Fi” will appear on the phone screen if you are connected. The stability and speed of connection however, will vary depending on your service carriers, your phone models and the network of your location. You can go to your local mobile phone service carriers to make further enquiries.
