I can in some respects the other reviews quite connect. The unit fits comfortably in your hand, is very compact and fits well in your pocket. The "trackpad" is quite mature, it takes hardly settling time and the navigation works so very precisely. Furthermore, the sensitivity of both axes of movement can be set separately.
The function keys on the sides of the device are meaningful positions and can be operated well. The speakers are also surprisingly good and above all set very loud (eg as alarm). The display is appropriate in size for such a small device. The configuration of the WLAN itself is for strongly encrypted networks so far without any problems (which even in computers is not a matter of course), if eg server certificates or other rather unusual services are required. This means that the WLAN can also be used in public networks. Only the automatic connection to already established networks works not entirely reliable, but is probably due to settings that I have not yet found.
The use of Bluetooth works well also, but nowadays really should require no more mention. The layout and operation of the menus are quite intuitive and easy, since there are hardly any complaints.
The photos, which makes the device are quite acceptable for relatively small camera.
For me, definitely, however, is too small, the keyboard. Many say they quickly get used to it, I can not confirm. I use the device now for about 3 weeks and I am still significantly slower than when I write on my normal phone with T9. In addition, the right cumbersome Entering umlauts in my eyes is a major shortcoming. There are so apparently adapted to other countries keyboards, so why not for Germany? It would also be convenient if there is an "old" key would be on both sides of the keyboard in order to actually use the multi function keys with both hands can. Overall, I find this keyboard so simply too small and impractical layout, but you have to make certain compromises, of course, if you still want to keep the phone handy halfway.
Furthermore, the device for my taste is a bit too weak equipped with processing power. This can be seen quickly if you call something more elaborate website or one of the larger apps start. Even the drive up to the installation of new software may take some more minutes. a 512 MHz processor is because vlt. not quite up to date. Compared to my current, no longer quite dewy phone (Sony C 510) (for example, a Java-based timetable app) are there in the same applications practically determine any differences, which even now a new device may not be actually for as , especially since it claims to be a "smartphone".
However, what most bothers me is that in my eyes absolutely inadequate equipment for mobile Internet use. Here is really no longer a comparison with current smartphone like the iPhone or HTC or whatever possible. In this category appears to me most clearly that it is in the device is a low-cost alternative to a full-fledged smartphone. As others have stated, the device does not have 3G functionality, which I think today is an absolute basic criterion for a smartphone. In some areas, especially larger city centers, one has indeed "EDGE", but, for example, for the use of card services, such as Google Maps is still much too slow. Something richer apps to be downloaded much more difficult. In addition, EDGE is even in smaller towns appear to be sporadic or not available (eg Münster, downtown). That leaves one then only GPRS, which is not even sufficient to load many mobile sites, such as the German rail or news sites common publishers. In addition, the included browser itself when used with fast WLAN problems in the presentation of content with Flash or Javascript and CSS content, which indeed nowadays actually no longer likely to be. Again, the page layout also takes sometimes quite long, what (waiting icon on the screen) is probably due to insufficient processor power.
One last gripe is the rather low battery life. Even if the device is turned on and no WiFi or Bluetooth use just lay at home, it's already happened more times that of the battery after a day (12h) was almost completely empty. By using mobile services or installed apps, the battery lasted through partly not even a full work day. My middle Ster has the same problem, it is presumably not necessarily on this particular device.
Conclusion:
Personally, I find the term "smartphone" for the BlackBerry Curve 5820 simply too high. The first point lack the necessary capacity for more demanding applications and, above all, a fast connection for mobile Internet use. Furthermore, the solution did not convince me completely without touch screen and the QWERTY keyboard, but I think that's probably a matter of taste.
Good contrast I find the easy and intuitive operation, especially this "Trackpad" and the multimedia equipment with mp3 player, camera, etc. All in all a nice device for example for younger users who are not necessarily on mobile Take the Internet, but rather want the phone rather the SMS write and use for entertainment purposes. Those looking for a full-fledged smartphone, will probably still have to look at a slightly different price category.
