I have the AT&T Service & the iPhone as well. I am somewhat bored with it though. My Roommater has just gotten a slider from Sony Ericsson. I can't work T9 or the numeric keypad too well anymore but I really like the setup & all the extra features on her phone. But I love how my iPhone can Sync so easily & I can only afford to buy another phone not another phone & an iPod.
Keep the iPhone or does anyone have any other suggestions on another phone for me?
