It would seem that 3UK are looking to expand their mobile handset portfolio and have plans to add the Apple iPhone to its lineup. In a recent blog post, it has indicated that they are looking to tie-up with the Californian mobile manufacturer.
…we’re asked a lot about our position with regards to the iPhone. We don’t currently have a commercial relationship with Apple but are working to change this during 2010 and add Apple to our portfolio.
Although 3 may have one of the best value-for-money offerings when its comes to mobile broadband and internet usage, their handset line-up has, to be fair, been pants. Things were improved upon last year with the introduction of the very popular HTC Hero which came with Spotify, but the rest of the line-up leaves much to be desired.

It seems odd that a company like 3, who is all about getting connected to the Internet, dont have the handsets that people want to make use of their infrastructure. Hopefully with a big name like the iPhone on the 3 network, it will drive more users to join them.
Personally, I recently unlocked my O2 iPhone and returned to the 3 network late last year, a great combination!
Iv got to agree with you… I left o2 and took out a 3 sim for the iPhone… Ots 10x better re speed and coverage.
o2 was a poor choice on apples part
