This one is great! You don't have to do anything other than download a small application to your mobile phone.

You know when you see statistics reported about mobile phone usage? For example, you see it reported that 26% of women play mobile games on their mobile phone. That sort of thing.

M:Metrics are the company that collate the information, but did you know that mobile phone users like you and I get paid to provide them with the data?

We'll M:Metrics are looking for more users in the UK to help them gather the information. The great news is that there's very little required of you. You simply sign up online, download a small application to your mobile and it monitors how you use your mobile phone. They don't monitor specific personal information such as your text messages or any of that malarky, the application simply tells them what you use your mobile for.

Now here's the free cash bit. They'll pay you £15 just for signing up. Then they'll pay you a £5 per month while you continue to let the application run on your mobile phone. Over a year that's worth £75!
