Recently, I’ve spent an unhealthy amount of time in the company of 3G dongles for our “Mobile Broadband Con” feature, which will be hitting the shelves on 11 February.

One of the aforementioned cons of mobile broadband is image compression – a process where the networks water down the images on websites to conserve bandwidth. The end result is that sites such as the BBC homepage look as if they’ve been dipped in the bath, and in my experience, the compression barely saves any time at all on page downloads.

Many networks allow you to switch the compression off if you wish. Virgin Media doesn’t, on the rather dubious premise that it’s helping customers stay within their data download limits.

However, there is a sneaky way to beat the Virgin image washout, which I accidentally stumbled across during my tests. Virgin piggybacks on the T-Mobile network, and if you download T-Mobile’s Web’n'Walk Accelerator software, you’ll find that it can be used to adjust the compression on Virgin, too.
