The instructions tell you to insert a new carriers sim card and then connect to iTunes. Easy enough.... but
Anyone have any idea if that means you can't swap sim's on-the-go? If you have 2 sims on different networks, will you always have to re-connect to iTunes after you swap them around?
Once it's unlocked, you don't have to do anything again... Mine is factory unlocked, and worked fine swapping sims when I traveled.
Will they check if the phone number has been used for the past year? Or is it allright to just buy a o2 sim on ebay and use that phone number?
It seems the main reason people want to unlock is to have low cost travel usage. Not to "avoid a carrier". Further they wish they could have the near unlimited data usage when they travel.
I mainly have a Pay and Go iPhone so that I can get the new model as and when it comes out on the 12 month cycle. So by the time I can officially unlock it, I will have a new one.
At least you should get a bit more for it on eBay if it's officially unlocked.
