I just started the BlackBerry 9300, and when I bought it, I was given the OS6.0 system. Please give us some comments (I'll give you all the main points after explaining).

1. There are three kinds of installation software. 1. Download the COD file, that is, ALX, with the boot program, and then identify ALX through the desktop manager and install it on the mobile phone. 2. Enter some websites through mobile phones and download them through OTA, that is, after clicking download, you will directly enter the mobile phone installation interface. 3. Download JAD program, in fact, the principle is similar to 2, JAD refers to a download connection. You use your mobile phone to browse to JAD put in your mobile phone, and then select Install, which will directly point to the installation connection. Of course, if there is a COD file next to the JAR, it will point to COD instead of a connection, so there is no need to download it.

Two. Third-party software doesn't surf the Internet, which is commonly known as Blackberry disconnection, but you are lucky to use 9300. At present, 6.0 systems including 9800, 9780 and 9300 can completely solve the problem of disconnection by mixing JAVA packages. As for the tutorial and the place to download the mixed brush package, you can search Beijing Xiao C through Baidu, and then search for "Blackberry to solve the topic of disconnection, including OS5 intermittent paste and OS6 mixed brush" in the search bar on the right side of the webpage.

Three. Let me make a general list of practical software. QQ, UDCALLER (where incoming calls and outgoing calls are displayed), Fetion Wizard (Fetion officially released embedded short messages are as convenient as sending short messages, so it is no longer troublesome to log in and log out with Fetion software), Wormhole, Google Maps, Blackberry Wings or official software download software APP WORLD, GTD(WORD and other document editing suites), QUICKPULL (deep restart to solve the problem that some software has been stuck in the background and cannot exit, Of course, if you don't want to mix brushes, disconnect the network and unplug the battery, you can use this software, so this software is also called simulated battery unplugging), memorybooster (memory cleaning software, which can be set automatically and manually), and finally recommend a weather forecasting software that can be used for free. Momo weather forecast software (by the way, there is a bug in 2.0.5. You can use DIY to push the icon to the desktop. You don't need to buy it. After setting it, save it and prompt you to buy it. Ignore them, quit, and you will find that they have been pushed to the desktop. Hehe, I won't say anything about ordinary people! )

If my pure originality can't get your choice, then I'm really blind.
