Right on this dialaphone website it says i can get a free PS3 if i buy this certain phone+contract.

seems too good to be true, i wondered if anyone had any experience of this website or heard anything about it?

Yep deal does seem too good to be true but it is true, lad at work has just done the same deal

Youll have to send off your bill every 3 months(i think) If you miss out sending one off then it voids it and i think you are then liable for the cost?

I know it works that way when they offer 6 months free etc.

The deal, is you get last years model of phone.. Its a fair trade off

I just got my New one through The Link (Yes they are still going), Nokia 6500 on Dolphin 40 and I had a choice of freebies.  I picked the Xbox 360 Pro + GTA4.  This year the deals have got silly.  Ive only picked that tariff as well because I can get 40% off through work, but no freebie if I go through work.  

Decent Websites to check are ::

http://www.thelink.co.uk
http://www.cpw.co.uk (Carphone)
http://www.mobiles.co.uk (Carphone, but under another name with better freebies)

Dialaphone be warned is part of Caudwell Communications (Phones4U).  Personally from experience I wouldnt trust them to actually send you the phone out, nevermind the PS3/360/Laptop or whatever you get free.
