I would be buying on PAYG so shouldn't be a subsidy as price is the same as it is from Apple? The difference Is apple have a 3 week+ wait and tesco mobile have some in at a few of their stores.
Since Tesco uses the O2 network anyway, though, you can use an O2 SIM in a Tesco phone.
if you buy a sim free iphone from apple then it is sim free for life
if you buy it on a network then it is locked to that network out of the box, and if you buy it from a store then they activate it for you anyway so it would lock it then and there if it werent lock out of box.
how the locking works: everytime the iphone is activated it sends off its IMEI or other unique device ID to apples servers that sent back the info to whether it it unlocked or if it is locked and to which network, if the sim card in it does not match the network it is locked to then it does not activate and you can only use the iphone as an ipod touch. - there is no lock to different network hack
What about buying a contract phone from the Apple store? Will it be locked or unlocked?
(I'm in Canada, and am wondering as the phone will be available unlocked from Apple Store and Apple stores here do offer the iPhone on contract)
I understand that but what I was asking is; does an O2 sim work in a handset bought from Tesco as the previous poster suggested? Tesco use the O2 network but does this mean the sims from the 2 companies are interchangeable? Has anyone tried it??
