Having been recently looking on eBay UK for the above phone I am asking for clarifiaction of what I believe to be true (or not) that: There is no difference between an unlocked phone and one that has been unlocked from a provider. i.e if I unlock a phone myself that's locked into o2 for e.g, then that's the same as buying an unlocked phone fromn the get go? Yes or No?

As the unlock code is just a 'number' or 'code' this would mean it's a software lock and not a hardware lock I assume, I would just likesomeone to clarify that has some knowledge for certain, so am I correct? Thanks

Dave

I don't see any difference personally. The only thing I recall is, the newer the phone the more expensive the unlock code can be, so you may get a cheaper handset by £30 and then end up spend £30 to unlock it - a false economy in that sense.

Don't confuse network unlock with bootloader unlock. Be aware that an O2 PAYG is SIM locked which can easily be unlocked but will have locked bootloader. You need to open the dialler and enter *#*#7378423#*#* to access the Service menu then Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says “YES"

@aspergerguy : That's exactly why I was asking: one phone I'm looking at is on the o2 network, so as I understand it all I would need to do is unlock the NETWORK and it would be the same as an unlocked phone yes? The install of SFOS required and unlocked network as I understand it, so there's no reason to ignore phones tied to a network?

The installation of Sailfish OS requires an unlocked bootloader. It is not uncommon for carrier-locked (also known as network-locked etc.) phones to also have a locked bootloader to thwart subversion of the carrier lock. I assume the recommendation has it's basis in this, but cannot rule out that there are more reasons behind it. Whether or not removing the carrier lock as you describe also makes it possible to unlock the bootloader, if that was even disallowed from the beginning, is something i don't know. I would however guess it does not. (i.e. it could still be a bad idea to get such a phone)

This:

" It is not uncommon for carrier-locked (also known as network-locked etc.) phones to also have a locked bootloader to thwart subversion of the carrier lock. "

is exactly what I didn't know, maybe the prior poster put this across but I didn't twig, however . . . . . . if a seller describes the phone as 'unlocked' they're describing the network, not the bootloader, nobody advertiises a phone on ebay and puts that - so the question would have to incliude -

can the bootloader be unlocked if it's not already ??
