Upgrading to a faster internet connection (Broadband/Adsl)....
If there is no broadband/adsl in your region, I know of GSM internet access using a USB-connected modem via "internet-mobile" cards that connect with some 256 kbps which would give you at least some 20-25KB...
From the side of the application you run already on the max. possible....
