Hello All, I've had my iPhone since the 29th, and l love the thing more every day. Thus far I've only charged via wall outlet. However yesterday I decided after I synced the unit I'd leave it plugged into my Macbook to charge. After about an hour of charging, the screen heated up to the point that I couldn't press it against my face to make a call. Rough estimate, I'd say it was 100+ degrees (I'l try to reproduce and verify this temp shortly). This doesnt happen when charging via wall outlet. Has anyone else experienced this?
