JailBreaking and Unlocking is a very simple process for some and others feel its just as easy to go to a shop and pay, however with that in mind many most likely put it off as an expense best kept.
My idea is simple and makes the hole process painless and nobody has ever done this before.
Customers wanting to have their iPhones unlocked would simple book a time and date allowing a 15-30 minute window for an operator to arrive and unlock their phone.
...and how are they going to do that... simple, through remote desktop.
All the customer has to do is connect their iphone as normal to their PC or laptop, the operator would connect to the customers computer through remote desktop and using such software as redsn0w put the iphone, ipod or ipads into DFU mode and run the jailbreaking program and or anything else they may have booked at the time...Unlocking etc...
The only obstacle I foresee is setting up a good order page (webpage) with various option such as operating systems, device current versions and of course a time and date that suits each party.
Perhaps a small window of 9-5 Mon-Fri to start of with until word gets around the net and others start to copy your business idea
For legal purposes your not selling a phone unlocking service, your selling your time for which I don't think anyone would mind paying 10euro.
So what do you think about that OneIdea, I would do it myself only I don't have the spirit in me to start another website.
