| Don't forget about Telcos. Your AT&T, Vodafone, Verizon & Co, put an enormous amount of pressure on Apple to limit and protect device unlocking. This is a cat & mouse situation where either party might benefit from tight unlocking controls. For example, MVNOs benefit from manufacturers with flexible and open unlocking policies that make it easy to unlock devices (without approval from the original operator), whereas long-term commitment contracts with traditional operators want to make it as hard as possible for you to leave with an unlocked device (regardless of whether you are legally entitled to or not - but that's a different story). The economics of whether Apple would benefit from less strict unlocking policies (ignoring Telco's wishes) are not that clear. You might think that unlocked devices would have longer lives, and therefore limit Apple's ability to push a new one to you, but you could also say that giving phones 2 or 3 different owners in their lifespans could help with app store purchases, limiting jailbreaking and possibly avoiding going with a newer less expensive android version. Disclaimer: We unlock phones for MVNOs and individuals who get bullied around by their telcos. Edit: Spelling |
Lock restrictions only come into play if you want the mobile network to subsidize your phone.
