The folks at 2degrees are preparing a full on assault on the small business mobile market. One of the first steps in this battle is their Biggest Bill Challenge. The idea is for kiwi's to submit their mobile phone bills, with prizes going to the biggest.

You can upload your bill in either a JPEG, PDF, Gif or PNG file formats. The bill can be from no earlier than 1st April 2011.

The prizes up for grabs include:

- 1st prize – A 2degrees $149 plan credit until 2020

- 2nd & 3rd prize – An LG Optimus Black handset

- Every entry goes into the draw to win one of 5 Pocket Wifi devices

At the time of publishing, $110 was the nations largest, but this seems unlikely to last, especially with one of our team members having a $700 bill themselves.

Submit your oversized bill or see the current leaders here.
