I have to agree. If the phone doesn't work take it back get a refund and cancel the contract.

These myths of one coder being so valuable that he/she can't be replaced are just untrue. When they are gone people either pick up the code they left behind or if it's incomprehensible it gets rewritten. If you really feel as a manager that you have to keep someone on your team who can't play nicely with other people then it's your responsibility to make sure they don't do any damage to the company or their coworkers.

You don't know many teenagers do you?

And to be fair. The people who paid 99cents for the app got an awful lot of free SMS messages...

As I mentioned in an earlier comment. If they got into the top 10 as they say they did and they were there for 11 days there must have been a significant number of downloads of the app: 20-30 thousand maybe? All sending hundreds of free SMS a day (it's free after all!). So that's an extra 2-3 million messages being sent on a daily basis...

Makes my sales statistics look a bit rubbish.

So they were in the top 10 paid apps for 11 days. According to here if you are in the top 15 paid apps you'll be selling at least 2836 units a day. According to my maths, after Apple has taken their cut they'll have made about $20K Not bad...
