I had the iphone too, I was never bored playing with it. But I killed that battery just writing messages. I couldn't stand carrying around one of those USB chargers days that I was out of my house for more than 12 hours. The Iphones battery SUCKS. The BLackberry battery (even though VERY similar to the iphones) Lasts a LOT longer. You won't be upset, unless you're obsessed with playing with touchscreens, cuz then you might just not like the bold. BUT YET there's still a Storm for all that touchy clicky feeling :D.
