Thx for all the replies...
After looking at some of these phones in detail, I think it has come down to the E90 (most likely), E61i, or possibly a blackberry (cheapest, easiest to set up through ATT). Some of the HTCs look intruiging, but I really don't like the interface and I am not a fan of WinMo. Plus I have no experience with them and the screen on the Tilt looks like it could snap off at any moment lol. After having my
N95 for a few months, I really love the new Symbian OS and I think it is a lot more intuitive for a Mac user/mother haha. I think she'll love her new phone. Thanks again!
