Not sure if this counts but having been CERTIFIED from the hardware vendors, manufacturers, trained on Software, access to tools and software that the average joe wont have, hardware repairs, and even building and maintaining the wireless networks I think Its safe to say I know my Sh**.

We had 2 identical model iPhones, one was factory unlocked via carrier (costs approx $50 bucks) and the second was unlocked via Jail break which can be done at your average Fli market, by any average Jo.

The factory unlocked model worked fine, the one that they used the unofficial tools to unlock and jail break, was piss poor in terms of reliability. It would freeze, crash often, it would loose signal. Now NOT every jail break is like this but it is something that you open yourself up to. Once you jail break your phone cant get software updates via itunes so it will have more bugs/crashes and compatibility issues., where as the factory unlocked can easily be updated via itunes no issues.

Not saying dont jail break, just know that your phone does have more of a chance of having these issues, maye not brick your phone permanently, but definitely problems can happen.
