Please do note that technician in this sense doesn’t mean that you can combine parts from 20 different obsolete unlocked iphone 4 parts and manage to create a newer better version of the original. Technician in this sense is someone who is fairly intimate with the inner workings of the software end of the iphone, and has extensive knowledge about processes such as unlock iphone 4, without so much as a raised brow and a browser open and pointed towards google.
The technician that I’m specifying are the types that know the difference between the unlock iphone 4 4.3.5 and a usual iphone 4 unlocking. As well as the subtle differences in the security systems where 4.3.5 has that slight chance to decommission your phone and sim card permanently if done wrong.. A technician is not an easy job, but after you’ve learnt how to do their work. People will be lining up to look for you to help them increase their battery efficiencies or other favours in exchange for your knowledge.
