It's hard to say how many people went out and bought a new phone versus replacing their battery due to this issue. I know anecdotally speaking that a number of our customers came to us after we published these results and said exactly that, that they had had a slow phone, that they had been confused and thought simply that it was time to upgrade, so they went out and purchased a new iPhone, realizing now in hindsight that they may have been able to replace the battery and have a phone that operated much faster than it had before.
I do know several analysts who have commented that this iPhone battery replacement program, the severe discount that Apple introduced in December, could have a material impact on the number of iPhone units that Apple ships this year.
