already 2 checks ahead of the competition ...
after a situation last year where despite having 12 phones which powered up, not one could be used because of network locks) I vowed to never have a network sold phone again.
Quite aside from the network locking is the SHITE they bundle with the phone you can't dump (I *still* don't want a Facebook app).
Hence I am happily rocking a Wileyfox Swift - brilliant device. Not locked. No shit.
