The Oneplus One is now available for 24 hours to purchase without an invite. It is £229 for the 16gb and £269 for the 64gb version.
This represents good value but I do feel that in a months time or so there will be all the new phones and maybe it is worth holding fire.
If you want a Oneplus One head over now – https://oneplus.net/uk .
If you happen to own one of these phones, you will be receiving an OTA update for the Cyanogen rom. This is not lollipop but fixes for kitkat.
