Yes, but Chronic charges $150 which is about £90 and everyone knows him from the days of the Chronic Dev Team, why would anyone use someone who no one knows and who charges a lot more?
Everyone out there including your self have a fair chance of earning a income in the unlock market given you have the proper sources and knowledge to provide, its a open market with newcomers joining daily,
I kind of look at it like the "Gold Rush" of unlocks lol and its all about supply and demand at the end of the day and that is all time high since past 2years.
PS. You and I know chronic's work in jailbreak scene but trust me, 99% of the world doesn't know who chronic is or what even jailbreaking is....not to mention jailbreaking is no longer "Cool" (aka useful as it use to be -- Unlocking, tethering data, folder closer, sbsettings etc) as those features are now part of iOS and for unlocking there are permeant solutions available.
