I was finally able to get Deb her Christmas present last weekend, and instead of an iPhone I bought her a Blackjack II. It fit her needs better than the iPhone. Plus it was a lot less ;-)
One issue though: the battery lasted less than 12 hours. Not good for a mom on the run chasing a Toddler, a Tweener and a Teenager.
I looked around and found the problem on an obscure site. The issue was the 'beam' feature of the phone was sucking lots of battery power. This is the feature that allows someone to 'beam' you their contacts from their phone. Since Deb stopped going to bars without me, she doesn't need that any more.
Turning it off and she has had a full charge for the last 3 days. Cool.
