I recommend This simple server because it works faster at the rate of 500k and above. Though Droidvpn is a little bit preferable just that it might stop at anytime and it is very slow.
Should in-case you want to go through this process then i expect you to have a working BB plan or recharge #100 now and send BISDAY to 21600 for daily 3GB.
After which you set your device connections to:
*. APN: web.gprs.mtnnigeria.net
*. Ip Address: 127.0.0.1
*. Port: 8080
Then proceed by Downloading the Android simpleserver
Then go to your Simple Server settings and configure it this way below: (i.e after the downloading and installation)
*. Pdproxy host: 10.199.212.2
*. Proxy port: 8080
*. Injection method: get Injection
*. Querry/url: http://web.blackberry.com
*. Injection host: web.blackberry.com
*Injection line press your keyboard enter key 4times
*. Log level: debug
Then close and try to connect to the internet and watch your browsing speed.
You might be wondering whether it works on just operamini but it works on both with opera mini, and Google Playstore. And also watching of video is applicable.
Wants to power all your application, just download PdProxyDroid and then enter the following configuration.
Full Configuration on Proxydroid
*. Host: 127.0.0.1
*. Port: 8080
Just close because you are done.
For those on Symbian and Pc, using Simple Server, just use the same settings
